Make A Baby Blanket With Two Triangles

Yep! I know it looks like four triangles, but it is only two! This whole blanket is worked up using two triangles in three different colors.

I used Lion Brand Yarn Basic Stitch Anti-Pilling in Silver Heather, Mustard, and Ecru.

I recently used this yarn to make another blanket called the Simple Stitch Blanket, and if you like this yarn, you’ll definitely want to make this other blanket as well!

What you’ll need: You will need a little less than three skeins of each of the Mustard and Ecru and one skein of the Silver Heather to complete this entire blanket, a size 6 mm crochet hook and some extra time.

I will explain more about the construction below in the pattern, and even designed a chart that will make it easy to see how the blanket goes together.

You can make this blanket… Promise!

The Crochet Stitches You’ll Need to Know

For this entire design, I used just two crochet stitches… the Herringbone Half Double Crochet (HHDC) and Single Crochet (SC), which are both easy to learn! Don’t worry, I’ll explain them below and also link to a video tutorial for them too!

Stitch Lessons

Herringbone Half Double Crochet (HHDC):

  • yarn over
  • insert the hook into the stitch indicated
  • yarn over (3 loops on hook)
  • pull up a loop and pull that loop through the first loop on the hook (2 loops on hook)
  • yarn over
  • pull through the remaining two loops on the hook
