how to join crochet granny squares together

There are various ways of joining granny squares together and I have done a lot of techniques and methods. There are methods that involve actually crocheting the pieces together and many methods of sewing them together with a needle and yarn.

My preferred method is crocheting the pieces together as I don’t have to guess how much yarn I will need to sew up x amount of squares. With crocheting the squares together, I will simply work from the ball of yarn I have and snip the yarn when I’m done joining a particular row of squares. No guess work there.

The method I’m going to show you is a bit of a mix between the single crochet method and invisible seam method. The invisible seam method actually involves a yarn needle to complete, but I thought I could combine the single crochet method to make it easier.

This method makes a ridge along the backside of the squares, but the front of the squares lay very flat and gives it a nice clean look.

To join the squares, use the hook size you used for making the granny squares. If you tend to crochet very loose, you may want to go down a hook size to join.

Step 1: Hold two squares together the wrong sides facing out and the right sides facing each other.

Step 2: Find the corner chain closest to the side you want to work on first.

Step 3: Insert your hook through the chain on each of the squares. Attach yarn, chain up 1, and single crochet into the same space

Step 4: Single crochet into outer loops only – continue this all the way across. (This picture may be confusing as both squares are red and previous photos I have one red and one white.)

Continue to pick up pairs of squares and join them together, you do not have to fasten off until you finished a whole row of squares you would like to join together.
