Make Some Mitred Squares

Thank goodness for Amy Kaspar and her calm, sensible instructions.   Here she shows us how to make mitred squares…

Squares are very common in knitting; they are the perfect (literally!) shape for knitters because if they just want to cast on and knit until something is square, they can take the corner of the work and fold it up to the opposite corner of the work still on the needle. If the sides are the same size, bind off!

Mitred squares are even more perfect because they do the work for you. They are also an easy enough project for a beginner, but can be made interesting enough for even the most finicky of knitters. You cast on two of the four square sides, and strategic decreases cause the knitting to end at a point exactly opposite the middle of the cast-on row. Magic.

Ready? Sweet…you do not need many supplies. Grab a pair of needles, a ball of yarn, and only one stitch marker. There are other ways to make these squares, but let’s set the benchmark at beginner level and get more complicated later.

Cast on an even number of stitches, placing the marker at the exact halfway point of your cast-on. I used 36 stitches, so I have eighteen stitches on each side of my marker. Repeat the following two rows:

  1. K to 2 sts before marker, k2tbl, slip marker, k2tog, k 2 end.
  2. K all sts

When you have two stitches left, just turn your work around, knit those two together, and knot your tail through that last stitch to bind off. It really is that easy.

Other than the knit stitch and casting on, the only two stitches you need to know are “k2tbl” and “k2tog,” and the mitred square is great practise for both. To k2tbl, or knit two stitches together through the back loop, insert your right hand needle into the back loops of both the first and second stitch on the left needle from right to left, and knit them together.

Did you see how the needle went into the stitches? Then, to k2tog, or knit two stitches together, insert your right hand needle as if to knit normally, through the second and first stitch on the left needle from left to right, and knit them together.

K2tbl causes a left-leaning decrease, and k2tog causes a right-leaning decrease. With these decreases leaning toward each other, they aid in pulling the sides of the work together to form a point when you have only two stitches left. Also, since garter stitch is more…well…squat than stocking stitch, knitting on both sides will cause an almost perfect square.

When you sew a bunch of them together, the weight of the other squares helps them to keep their square shape, so you may not have to block your squares at all. More knitting, less soaking. You do have to have a bit of faith, though; these squares look a bit like a falcon face when you are about halfway through, but keep knitting.

If you ever lose your place, no panicking necessary. Either use your tail as your guide – I knit back when my tail is to the right, because I do a knitted cast-on – or look at your stitches. If you are facing two stitches next to the marker that have a slightly larger gap than the rest of your stitches, or you can see the two purl bumps sitting on the stitch facing you, then you know to knit back with no decreases. See the double bumps, below?

While there is technically a right and wrong side, it ultimately does not matter. Garter stitch looks the same on both sides, so choose your favourite look where the decreases occur. This is what the technical right side looks like.

A finished mitred square is whatever size you want to make it. Your cast-on edge indicates both the height and the width of your finished square, since the row takes up two sides of the square. If you want a seven-inch square, cast on enough for fourteen inches’ worth of stitches, or twice as many as your stitch gauge.

“Why would I want to knit another square?” you ask? Here’s why. If you do not know what to do with variegated yarn, leftover sock yarn, or remnants of two balls of yarn, you can do fun things like this:

The above photo is two worsted cottons, one solid and one variegated, striped by alternating two rows of each colour. You can certainly use this pattern to make afghan squares and dishcloths, since they are both square, but you can seam them together (or, if you are feeling super-adventurous, pick up stitches on two sides of already-made squares) to make all sorts of items.

Make a dozen of them and sew them together for a scarf. Make two eighteen-inch squares, seam them on one side, fold it in half, and seam sleeves to make a shrug. Make two of the same size and sew three sides together for a handbag. Make six and seam all sides together like a cube, stuff it with poly-fil, and make a colourful children’s toy. Make a super-giant square and call it a baby blanket.

Mitred squares are just another new way to make a building block for something else. Once you learn the technique, look at your stash and let the creative juices flow. Oh, and yes…yes, that is a cup of coffee next to my knitting. If you panned out on every single photo in my blog posts, I assure you, that coffee cup would be there.

    Thanks for the reminder tutorial on mitred squares. I made some long ago but you have renewed my interest. Oh! the possibilities are endless.

  2. Jean says:

    Several years ago I made a couple of these squares but had no idea what to do with them. You’ve renewed my interest..I can see several projects in my future. THANKS

  3. Rebecca Dickson says:

    Thank you for this – wanted to make one of these squares for a while. Just one question; do you decrease on every row?


    • Amy Kaspar says:

      Miss Rebecca…Amy here…You decrease twice on one row, and then knit back on the other row. If your marker is in the very center as it should be, then on the right side, knit to two stitches before the marker, knit the two stitches through the back loop (left-leaning decrease), slip your marker, knit two together (right-leaning decrease), and then knit the rest of the way. The other side is just knit-knit-knit!

  4. Lauren says:

    This is lovely!!! Thank you! I’m having some trouble, though. I’ve tried this with two different types of yarn, each with their appropriate needles. I’ve tried this method, and also the method where you centered double decrease (s2kp2). It doesn’t matter with method I use, though. Every time, the shape looks more like a kite (the top of the kite being the two cast-on sides, and the tail of the kite being the unfortunate last few rows of the “square”).

    Do you have any advice??? I’m dying to use this beautiful yarn to make an afghan for my dear friend who is moving across the country, but I can’t seem to work it out. I’m about to give up on the mitered square altogether.

    • Amy Kaspar says:

      Miss Lauren…amy here…if I were a betting girl, I would guess that either you are doing these in stocking stitch (in which case your gauge will have to accommodate for the longer stitches), or you need to go down a needle size or two. Since garter stitches tend to be so squat, you might need to tighten your stitches on a smaller needle to make them even squattier (it’s a word). If this doesn’t work, shoot me an email to with a photo or two, so I can help you come up with different ideas.

  5. Nathan says:

    This is the easiest mitred square pattern I have used but mine isn’t square but looks like a kite type shape with the end part being the tail end of the kite. I used two strands of DK wool on 5mm needles using St-St. I have been knitting for years and it’s so frustrating at why I can’t seem to get it right. Please could you advise me?

  6. Laura says:

    To make this square garter stitch is used. Which means knit all rows.
