How to Crochet a Corner Square

How to Crochet a Corner SquareSquares are fun to work with and make! Really fun! There seems to be infinite variations of squares. You have granny squares, lacy squares, solid squares, tiny squares, huge squares the size of a blanket! We are going to make a corner square. Huey Lewis and the News may say it’s hip to be square, but we know it’s hip to make squares!

What you need to make a square

Also known as a crocheted mitered square, a corner square begins in its corner and works outward from there. So, don’t think you need to know anything about miter saws or math to make a square! Some scrap yarn and a comfortable hook is all you need to learn how to make a corner (mitered) square.

Of course, squares are very versatile too. You can sew small squares together into a fabric to make apparel or home goods or you can make one big square to use, as previously mentioned, a blanket! That’s one big square! In fact, if you search crochet squares on Pinterest, I’m pretty sure the results are almost infinite. Isn’t it great!

Here’s a very basic crochet square using only single crochet although you can make squares using other stitches as well. If you don’t know how to single crochet, you can learn how here. If you already know how to single crochet, grab some yarn and a crochet hook and let’s crochet!

Begin with 2 chains on your hook.

Row 1: Single crochet 3 times in the second chain from the hook. Chain (ch) 1, turn.

Row 2: Next, make 1 single crochet (sc) in first stitch, 3 sc in second stitch,  1 sc in last stitch. Ch 1, turn. It doesn’t look like a corner at all! Don’t give up!

Hold onto your square!

Hold your work with the beginning corner pointing downward as you work. It will look more like a diamond than a square as you work, but who doesn’t like diamonds?

You can continue the pattern and make your square as big as you want! It’s up to you to decide when your square is finished. I’m stopping after 10 rows because it seems like a nice enough square.

They can be sewn together or maybe stand alone and used for coasters! You can make several and flip some of them as shown above so the rows make different patterns when they’re joined.
