How to Knit a Mitred Square Blanket

There are lots of different ways to knit a mitred square. This is how I knit my Mitred Square Blanket. I chose to use an analogous colour scheme of green, turquoise, teal, blue, purple, cerise as much as possible. Most of the yarns are either hand dyed: semi-solid, tonal, variegated, or commercial self patterning. A few other colours did creep in as part of a multi coloured variegated yarn or commercial sock yarn. These just add an extra sparkle to the finished blanket. I loved the tiny touches of orange, red, brown and zingy green.

Mitred Squares Blanket Pt3 5

This is a long post as I’ve taken lots of photos. I know that for many people I may go into too much detail, but I like to do the tutorial posts so that they will enable a beginner knitter to be able to do the project. This is actually a great project for a beginner as the mitred squares are easy to do.

Mitred Squares Blanket Pt3 1


Assorted leftover sock yarn from other projects. I have also used 4 ply yarns. I have used the same colours between one and five times in a couple of cases. It really depended upon how much yarn I had. This project could also be done rather beautifully with a few colours of a long repeating yarn like the Lang Jawoll Magic, Lang Jawoll Magic Degrade, Schoppel Wolle Zauberball or Crazy Zauberball if you don’t have lots of sock yarns. It would also be a fun project for a knitting group who could swap sock yarn leftovers. In all I used about 75 different sock yarns in my mitred squares blanket. I adore how the repetition of the yarns the a cohesive look to the blanket.

Many people refer to their Mitred Square Blanket as a Cosy Blanket or a Memory Blanket. I look at the squares and can remember what each yarn was used for. I’ve used these yarns to knit socks, hats, shawls, fingerless mitts as well as knitting outfits for Sasha or Gregor dolls. But to be completely honest, I adore my blanket, not because of these memories but because it was a pleasure to knit and I chose to knit the blanket in my favourite selection of colours from my stash of leftover sock yarns.

Mitred Squares Blanket Pt3 10

Size of My Mitred Square Blanket:

The finished size of my mitred square blanket is 105cm (42″) x 140cm (56″).

Each mitred square weighs 6g. I didn’t worry if I hadn’t enough yarn to finish a square, I just used a different yarn to finish the square.

My Mitred Square Blanket is 11 squares x 15 squares in size (165 squares). It weighs approximately 1 kilo.

Each square measures 9.5cm x 9.5cm (3.75″ x 3.75″), but as the blanket grows in size the squares stretch a little bigger due to the weight of the surrounding squares.

My only rule when choosing which yarn to use next was that the same yarn shouldn’t be used within 2 blocks of each other.

Mitred Squares Blanket Pt3 3


I used two 3.25mm (US 3) 20cm (8″) long Clover Takumi bamboo double pointed needles. You need to have the double points. I prefer the bamboo needles as I find them easier on my hands when I’m doing a lot of knitting. There is a lot of knitting in a mitred square blanket. The other good thing about the bamboo needles is that they aren’t as slippery as a metal needle so the stitches don’t slip off, even when there are only a couple of stitches on the needle. This is so handy when the blanket is being put away after you’ve finished knitting on it.

Other notions used: a locking stitch marker or safety pin and a stitch marker. If you’d prefer to sew in your ends a tapestry needle. I knit the yarn ends in as I went along and then snipped the ends to about 1cm (0.5″) long. The photo below shows the wrong side of my mitred square blanket and I think it looks reasonably neat. I don’t mind the odd little end.

Mitred Squares Blanket Pt3 8

How I Knit My Mitred Square Blanket:

I’m sure there are lots of different ways of knitting the mitred squares, this is how I did mine. I knit my squares in normal garter stitch as I wanted my blanket to be soft and fluid. You can tighten up the squares by knitting every stitch through the back loop. This causes each square to be a bit smaller.

Mitred Square 1:

  • Using the 3.25mm double pointed needle, cast on 48 stitches, I used a long tail cast on.
  • Row 1 (WS) : knit 24 stitches, place marker, knit 24 stitches.

Mitred Square Blanket Tutorial Step 1

  • Row 2 (RS): knit to 2 stitches before the marker, k2tog, slip marker, k2tog, knit to end.

Mitred Square Blanket Tutorial Step 2

  • Row 3 (WS): knit

Mitred Square Blanket Tutorial Step 3

  • Repeat rows 2 and 3 until 2 stitches remain.

Mitred Square Tutorial Step 4

You’ve finished your first mitred square. This is square 1 which is in the bottom right corner of the blanket.

Mitred Squares Blanket Pt3 6

Mitred Square 2:

The joy of knitting the mitred square blanket is that the squares are joined together as you go, so no sewing together of squares and minimal finishing.

Mitred Square Tutorial Step 5

Square 2 will be attached to the left edge of square 1. With the right side of square 1 facing you, knit the 2 stitches remaining on the needle of square 1 using your new sock yarn colour. This is the first stitch. Pick up and knit 23 more stitches along the edge of square 1.

Mitred Square Tutorial Step 6

I chose to knit the ends in as I went. Some people may prefer to leave them loose and weave them in later.

Mitred Square Tutorial Step 10

On the first row, as I pick up and knit the stitches (along the edge of each garter stitch ridge) I weave in the yarn end from the previous square, for the first 10 stitches. The photo above shows the wrong side of the square where the yarn end from square 1 has been knitted in along the edge.

Mitred Square Tutorial Step 7

When I’m nearing the end of this edge, I count how many stitches I’ve made and how many garter stitch ridges remain, if you have to, you can miss out a ridge to make sure the final stitch is on the corner of the square.

Mitred Square Tutorial Step 8

When you have 24 stitches along the edge, place the stitch marker.

Mitred Square Tutorial Step 9

Then cast on 24 stitches using the backward loop cast on using your working yarn.

Mitred Square Tutorial Step 11

This is the right side of the mitred square blanket.

Turn, and knit one row (wrong side). The second square is knit exactly like square 1 from this point on. Starting with Row 2. Remember to knit in the yarn end for square 2 on this row.

Mitred Square Tutorial Step 12

  • Row 2 (RS): knit to 2 stitches before the marker, k2tog, slip marker, k2tog, knit to end.
  • Row 3 (WS): knit
  • Repeat rows 2 and 3 until 2 stitches remain.

Mitred Square Tutorial Step 13

Cut the yarn end about 20cm (8″) long. Place the two stitches on the locking stitch marker or safety pin.

Mitred Square 3:

You are ready to start square 3 which will be attached to the top edge of square 1.

Mitred Square Tutorial Step 14

Using sock yarn 3, cast on 24 stitches using the long tail cast on. Then place the stitch marker.

Pick up and knit 24 stitches along the top edge of square 1 through the edge of each garter stitch ridge. Remember to knit in the ends in the same way as for square 2.

Mitred Square Tutorial Step 15

As you are nearing the end of the top edge of square 1 remember to count the stitches you have made and how many garter stitch ridges still remain. Try to have the 24th stitch in the ridge beside the joining edge between square 1 and square 2.

Mitred Square Tutorial Step 17

Turn, and knit one row (wrong side). Then knit square 3 in the same way as square 2 beginning on Row 2 (the right side).

  • Row 2 (RS): knit to 2 stitches before the marker, k2tog, slip marker, k2tog, knit to end.
  • Row 3 (WS): knit
  • Repeat rows 2 and 3 until 2 stitches remain.

Mitred Square 4:

Mitred Square Tutorial Step 16

All internal squares in the mitred square blanket will be knit in the same way as square 4.

Mitred Square Tutorial Step 18

Pick up and knit 24 stitches along the left edge of square 3, place the stitch marker, then pick up and knit 23 stitches along the top edge of square 2.  When you reach the 2 stitches that were left on the locking stitch marker, knit the 2 stitches together, this is the 24th stitch on the top edge of square 2. Remove the stitch marker.

Mitred Square Tutorial Step 19

Turn, and knit one row (wrong side). Then knit square 4 in the same way as square 2 beginning on Row 2 (the right side).

  • Row 2 (RS): knit to 2 stitches before the marker, k2tog, slip marker, k2tog, knit to end.
  • Row 3 (WS): knit
  • Repeat rows 2 and 3 until 2 stitches remain.

Mitred Squares Blanket Pt3 4

The mitred square blanket was photographed at the lodge that we stayed in for a week in the Cairngorms. This was where we took the photos of the gorgeous and acrobatic red squirrels. We got great photos, they were pleased with their payment of peanuts and hazelnuts that we had brought with us. We brought quite a lot of shelled peanuts and hazelnuts as well as peanuts in their shells with us and used all of them before we left.

Mitred Squares Blanket Pt3 9

This is a nice sized blanket, big enough to snooze underneath on the sofa, or to throw around your shoulders when you are outside.

I chose not to add a border to my blanket. This was partly because I was thinking of making it a little bigger, but actually, I like how the edge looks. I have thought about doing an applied I-cord edging like I did on my mitred square scarf. Still not sure! What do you think?

Mitred Squares Blanket Pt3 11

I love hearing how you enjoy knitting the patterns and look forward to reading your comments here and on our Facebook page.

About Nicolette


  1. love your blanket do you have a book to buy with you pattern in it ? thank you betty

  2. I love your Mitred Square blanket and the colors you used. I don’t do socks but I plan on making myself a Mitred Square blanket just for the pure love of it. It looks so comfortable and I understand you liking the feel of it on your lap as it grows larger. I have several projects already planned but I am going to get some sock yarn and the bamboo needles you suggested using and start on the blanket. I think I will put a border on mine. I like quilts that have borders and think I will feel it has a more finished look by adding a border. I want to use a lot of blues to purples into the pinks and a few of the other colors in mine and I can see it with a “warm” navy border. Thank you for a great tutorial. I have seen photographs of a Mitred Square blanket and thought I could never make one like that. I am not a real fast knitter either, I knit for the enjoyment of it not the speed. I love the little red squirrel, I have bunnies in my yard at the moment. Mama has at least 2 tiny babies now. The squirrel will arrive later when the nuts from my hickory nut tree are ready to be picked. They get all of the nuts and I love watching them bury them in the yard and then come back to get them in the Winter.

  3. Amanda Diltz says:

    Love your tutorial!! I have to say, I’m obsessed with your Matryoshka doll stitch marker shown in your photos here. Where did you find that?? 🙂 <3

  4. Peggy Piper says:

    Thank you, so much for your great tutorial. I’ve done some domino knitting in the past. Printed tutorials are my favorite. I love your detailed steps with all the pictures. I like your method of leaving the last 2 stitches on the current square to join with the new square. This results in a better/stronger “anchor” to the prior square. I use worsted weight yarn with a Size 10 (USA) needle-but am trying smaller needle sizes.

  5. mary henaghen says:

    I am thinking of doing this with new yarn, not scraps. What would be the yardage I’d need to finish, I’ll be using 2 colors

    • My finished mitred squares blanket weighs approximately 770 grams. If you were using 100g balls of sock yarn you’d need 8 balls, but you could need more if you wanted to knit a larger blanket or to add a border on your blanket.

  6. Lynne Wilan says:

    Hello Nicolette and thank you for making so many photos so the tutorial is so clear. So often what we read and understand is different than what the tutor has written and means. You showed so clearly where to put the needle. Thank you so much.

  7. Carine Wolfenden says:

    Thnaks for this – Was so much fun to knit. I used Sirdar Big Softie on 12mm needles. I cast on 24 stitches at the start which kept the squares of a manageable size. I used just under 38 balls and took about 1 month.
    The 2 stitches left at the end of square 4 I simply put on a holder then used as 1 stitch of the next square.

  8. Thank you for sharing your tutorial. I have outlined my squares in black when I was picking up the stitches. It defines the hundreds of sock yarns used. I intended it as a waistcoat for my daughter but being so addictive it has grown into a large single blanket. I researched doing an I chord edge but shied against it -too much a labour of love! I I am now planning a dc edge with a shell finish

  9. Hi, I am in the middle of trying this for the first time. I have just started square 3, by the looks of things this will leave another 2 stitches left on a stitch holder at the top left hand corner of the square. In your description of picking up stitches you do not mention using these two stitches on the stitch holder. Am I correct or am I missing something? Should these two stitches be included in the original 24 picked up at the start of square four or just left?

    • I’m sorry I can’t really help at the moment as I’m not at home. If you look in the previous comments on How to Knit a Mitred Square Blanket you may see a similar question answered or maybe someone else will be kind enough to pop an answer into the comments. I haven’t got anything with me in hospital other than a sock to knit on.

  10. Could the mitred blanket be knit in chunky wool

    • I don’t see why not. I’d probably knit a practice square to see how many stitches you want to cast on, needle size, etc. You wouldn’t want too tight a guage as you want the blanket to drape nicely but it would be wonderfully warm and cosy when it is finished. May knit up a little quicker too. I think I’d probably knit larger squares rather than small ones as that would look nicer in the chunky wool.

  11. Thank you for this tutorial! Looks like easypeasy, but then again, I have not tried it yet.
    I am sorry for my bad english. I am from Finland and I don’t remember every word I learned in school, some 20 years ago… Anyhow, this blanket I will make.

    • Great. I hope you enjoy knitting the blanket. I’d love to see a photo of yours as you work on it. If you’re on Instagram please let me know and I’ll have a look.

  12. Can you please add a pattern, so I can print it out and refer to it when I need to? I cant keep scrolling down the whole thing. Thanks

  13. I’ve been wanting to knit a mitered square scarf. It’s been frustrating running into YouTube videos only showing the technique and not the whole process from beginning to end. I’m so happy you put the photos of the joining stitches part. Will start a scarf using these instructions!

    • Hi Mo
      Thank you. I used the same mitred square technique for knitting my Mitred Square Scarf. The main difference was that I used different sized squares. It makes a beautiful scarf. I’m sure you’ll love your scarf when you finish it. I’m so pleased you found the instructions helpful. Happy Knitting, Nicolette

  14. Hello Nicolette,

    Your blanket has been an inspiration for me. My leftover sock wool has now morphed into half a blanket and is still growing.

    When you pick up stitches along an edge (sock or mitre square) do you slip the needle under the two threads between ‘bumps’ to make a stitch or slip the needle under one? I’ve never been too sure on this.

    Thank you for your terrific tutorial.

    • Hi Penny

      It is a lot of fun knitting the blanket. At the moment I’m knitting two cushions for my mother-in-law for Christmas using the mitred squares.

      There is a single ‘bar’ between the bumps created by the end of the garter stitch ridge. The bump looks a bit like two pieces of yarn tied or twisted together on the edge. I put the tip of my needle beneath the twisted section of the bump so it goes underneath both of these twisted yarns.

      I found that if I made the stitch using the single bar that on if I didn’t knit through the back loop on the next row I would have little gaps. Even with that I wasn’t as neat as going through the little bump.

      I’m so pleased you’ve enjoyed the tutorial. I’d love to see a photo of your blanket.

      I’ll put photographs of the cushions I’m knitting on the Knitting Squirrel when they are finished. Best wishes, Nicolette

  15. Wow! What a fantastic tutorial! I’m working on two Sock Yarn Blankies and am knitting mine very similarly to yours. I’m just using different cast on numbers. And I finish off the square before picking up for the next one. Oh and I always skip the first stitch with the yarn in the front and knit through the back loop of the last stitch. That just gives an easier edge for picking up the stitches.

    Anyhow, I really love this post and will be sharing it with my group on Facebook. I also have a group on Ravelry called Sock Yarn Swappers. I post lots of different swapless swaps there. You simply sign up for the dyers you are interested in, pay the fee, and then I make & send you the minis. It’s a great way to build your mini skein stash. I feature a lot of great dyers every month but spots fill up quick. I’d love for you to check it out!

    • Hi Lisa, thanks for the information about your Facebook and Ravelry groups. They sound like a wonderful way of obtaining lots of different sock yarns for knitting the blanket. I like your suggestion for the first and last stitch. I must try that the next time I’m knitting mitred squares. Many thanks, Nicolette

  16. I have been looking for help with making a mitred squared blanket…… Every time I think I found one its a picture ugh such a pain when you are so interested in something you can’t find…….. Thank you so much for your tutorial……. Please keep posting tutorials they are great help……..

    • So pleased you found the tutorial for making the mitred square blanket helpful. What colours are you using? I must cast on for a new blanket soon, I love having a long term project on the go! Happy blanket knitting, Nicolette

  17. Hello Knitting Squirrel…..I love these mitred squares. I have managed to do four in a square. I am a novice knitter, so now I’m not sure which square to knit next! 🤔🤔🤔

    • Hi Hilary,

      That is great – congratulations on knitting your first four squares. You pretty much know how to continue. Once you’ve knit another couple they’ll become second nature!

      All the squares along the lower edge of your blanket, to the left of corner square 1 and square 2, are worked in the same way as square 2. I knit eleven of these including square 1.

      All the squares on the right hand edge of the blanket (above square 1) are worked in the same way as square 3. I knit fifteen of these including square 1.

      All the squares in the centre of the blanket (other than the lower edge and the right hand edge) are knit in the same way as square 4. My finished blanket had a total of 165 squares.

      There are different ways of knitting your blanket. I liked to keep it relatively rectangular in shape. So I would do a couple more Square 2’s, then, I’d do a couple more square 4’s above them. Then I’d do a couple more Square 3’s along the right edge, then I’d work more square 4’s to turn it back into a rectangular shape again.

      Once you’ve finished another few squares, you’ll get into the rhythm of knitting the blanket. It is very relaxing.

      I just made sure that the next yarn I chose wasn’t within 2 squares of it in any direction.

      Doing it that way, I was able to measure the blanket, every so often to see if it was about the size that I wanted it to be.

      I hope that helps. Happy Blanket Knitting, Nicolette

      • Hello again Nicollette.
        Thank you so much for your very full reply. I have now made nine squares in all! I am such a beginner. Your squares look so perfectly square and mine are a little more shall we say rustic😊 I was originally just going to knit one square just to see if I could. It looks as if I am now doing a blanket. My friend gave me some of her sock yarn ends( I don’t know how to knit socks yet) and I have bought some tiny 10g balls of sock yarn……I find it really magical how the knitting gradually pulls into a square and I can’t predict the pattern on each individual one. Thank you for inspiring me to have a go. Xxx

        • Hi Hilary, that’s fantastic! Once you’ve done a few it becomes second nature! Personally, I love rustic! All these things improve with practice. Id love to see a photo as you progress. Happy knitting, Nicolette

  18. Thank you for this tutorial – it’s in my winter to do list. I really love the squirrel 🙂

    • Thank you Mari. We were so lucky to be able to get so many photos of the red squirrel’s. The Mitred Square Blanket is such a great way to use up sock yarn! Happy Knitting, Nicolette

  19. Hi Nicolette,
    I have alot of tweed sock yarn I’m using to make this blanket! It’s the perfect project for it! I have a question for you on the edging. How many stitches would you use to make the I-cord edging for this blanket? 3 or 4? I’ve never knitted one before. Thank you!

    • Hi Karen, I’d use a 3 stitch I-cord edging. I used it for the Mitred Square Scarf that I made and I don’t think I’d have wanted anything bulkier than that around the edge. But when I’m not sure which will look best I normally try sampling both to see which I like better. The tweed sock yarn will look gorgeous as a blanket. I really hope you’ll email me a photo of your progress, I’d love to see your blanket. Nicolette

  20. Hi Nicolette,
    I have a lot of tweed sock yarn so I thought this would be the perfect project to make with it! How many stitches would you use to make an I-cord edging for this blanket? Around 3 or 4? Thank you!

    • Sorry, I didn’t answer your comment sooner. Had no internet or tv at all on Wednesday and internet connection has been incredibly slow and irratic since then. Very frustrating.

  21. I adore your tutorials. They are so clear. The detail makes ALL the difference. Thanks so much

  22. Adriana Caldwell says:

    Gorgeous. Thank you for sharing. I would omit an edging until you are satisfied with the size of your blanket. An I-cord edging sounds fabulous. Great pictures. Awesome tutorial. Wonderful location.

  23. Fantastic and clear tutorial. I’ve been meaning to do something like this with the left overs for ages. Time to get started…

  24. Carolyn says:

    Thank you for this tutorial! I definitely plan to make one in my future, it looks like a perfect project to work on a bit at a time 🙂

  25. Marty Ward says:

    Thank you so much for this tutorial! Very helpful. So you just keep making sections of 4 squares until the desired size? I love all of your tutorials

    • Hi Marty

      You just keep adding squares in the same way: Square 2 (is how you attach all the squares along the bottom edge of blanket), Square 3 (is how you attach all the squares on the right hand side of the blanket), Square 4 (is how you attach and knit all the internal squares in the blanket. They also become the left hand edge and the top edge on the blanket).

      It is great fun, no sewing up involved at all. The blanket just keeps growing in a wonderfully pleasing way!

      Hope you try knitting the blanket. It is a lot of fun. Nicolette
