How to Make a Modern Crochet Square Blanket

This crocheted blanket is worked with just one stitch and two yarn colors to create a four blocked square, modern looking design.

Easy Steps to Make a Square Blanket

  1. Chain the number of the blanket size you are making, work into the second chain from the hook
  2. Half double crochet into each chain across for half the number of stitches in the row
  3. Change yarn colors and continue half double crochets into each stitch across, turn
  4. Chain 1, hdc into the bl of each stitch across halfway, change colors again

Expert Tip: When you start a new color of yarn, you will always drop the yarn color when you are done working with it and then pick it back up when needed again. This will help form the crisp, clean edges of the four squares that will make this blanket feel modern.

The Yarn

This blanket is made with Patons Beehive Baby Sport, which is a lightweight #3, 70% Acrylic / 30% Nylon yarn. I recommend using a metal hook (G-4 mm), so the yarn doesn’t split. If you do find that it splits with the hook you use, I suggest trying a different crochet hook instead, since they are all shaped a bit differently.

I used the colors Baby Grey and Baby Grey Marble, so it would create a neutral crochet blanket that would go well in most nurseries and living rooms. If you’d prefer to make this blanket design with a different color, it will be easy since this yarn is available in a variety of beautiful colors.

Substitute Yarn: If you can’t find this yarn or would prefer to use a different yarn for this blanket, then I recommend Brava Sport by WeCrochet. Keep in mind that any lightweight 3 yarn would work perfectly for this easy blanket pattern.

The Stitches

This entire easy crochet blanket is made with just one crochet stitch, the hdc stitch, which a beginner crocheter could master in no time. Not only will you make a half double crochet, you will also be working in the back loop of the hdc stitch too!

Learn more about the half double crochet stitch and half double crochet back loop technique below.

Half Double Crochet (hdc):

  • Yo (yarn over) insert hook from front to back of the designated stitch, yo the hook and pick up a loop. 
  • Yo the hook and pull back through all three loops on the hook.

Back Loop (bl):

  • Insert the hook through the bl only of each stitch, rather than under both loops (the v) of the stitch. Complete the stitch as usual.
