What is a Mitered Square?

Mitered squares start at one corner and grow outwards on only 2 sides. This creates the distinctive arrow or L-shaped rows. Changing colors highlights the unique construction, so double crochet mitered squares are most often worked in multiple colors.

Mitered Squares in Other Stitches

You can make a mitered square using any stitch you like! The key for different stitch sizes is how you do the corner increases in the middle of each row. To keep the square shape, you need to add enough stitch width to match the height of the row. Try this tutorial for single crochet mitered squares!

The pattern shown in this tutorial video is my Around the Corner Mitered Square Waschloth pattern.

For this pattern and the tutorial, I used Lion Brand 24/7 Cotton yarn, which Lion Brand had originally sent me for free for other projects.

How to make a double crochet mitered square

The square starts in one corner, with 2 stitches on each side of a ch-1 corner space.

Row 1: Ch 4, (dc, ch 1, 2 dc) in 4th ch from hook (the 3 skipped chains count as 1 dc).

Now we extend the square, working only on these 2 sides.

All remaining rows: Ch 3 (counts as a dc), turn, dc in each st to the corner ch-1 sp, (2 dc, ch 1, 2 dc) in the ch-1 sp, dc in all remaining stitches.

Keep repeating this last row until your square is the size you want. You’ll notice that on every row, we are adding 4 stitches in the corner ch-1 sp. We started with 4 stitches on Row 1, so you can calculate the stitch count of any row by multiplying the row number by 4!

Single Crochet Edging

We have been working on only 2 sides of the square. On those 2 sides, you’ll see the pretty v-shaped tops of the stitches. But on the other 2 sides, you’ll see the sides of the rows. To give your mitered square a pretty finish, add an edging round! I like the low profile of a single crochet edging.

Edging Round: Ch 1, turn, sc in each st across to the corner ch-1 sp, (sc, ch 2, sc) in the ch-1 sp, sc in each remaining st across, ch 2 to create another corner. Now working in ends of rows, 2 sc in each row to the next corner – this will be the very first chain that row 1 was worked into. (Sc, ch 2, sc) in the corner ch, 2 sc in each row across to the end, ch 2 for the last corner. Finally, join the round with a slip stitch in the first sc, or try the invisible join shown in the video.

Optional surface crochet

I dislike the look of one color worked into the side of a row of another color. Unless you want a bunch of ends, it’s hard to avoid that with a mitered square edging. One solution is to cover up that transition with surface crochet! Simply make a surface crochet slip stitch at the bottom of each stitch along the edging round.

Finishing

Block your finished square for best results, and weave in the ends!
