What is Warm Up America!?

Before you get started on your square you may want to learn more about what Warm Up America is. Warm up America is an organization that collects rectangles and blankets year round as well as many other items such as blue hats for the HatnotHate program to donate to those in need.

All projects, crochet or knit that are donated to Warm Up America should be machine-washable. Most donations are in a medium/worsted weight, but any weight yarn will work as long it is the 7″ x 9″ rectangle, 9″ x 7″ rectangle or a completed afghan.

The Stitches For a Textured Crochet Rectangle

To crochet this rectangle, you will need to know how to half double crochet (hdc) as well as work that hdc into the second back loop of the stitch. The hdc is a basic crochet stitch that is easy to master which makes this an easy pattern to work up. The second back loop of the half double crochet may be the one part of the pattern you’d want to go over before you begin, so you know exactly where it is located.

Crochet Stitches for Textured Rectangle Pattern

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.

Half Double Crochet Second Back Loop (second loop hdc):

  • Worked the same as the regular hdc stitch but only through the second back loop of the hdc stitch.

The square pattern is created by crocheting a row of regular hdc stitches followed by a row of hdc stitches worked in the second back loop.

It is good to be familiar to where the front loop and the back loop of a stitch is so that way you can find the second back loop of the hdc as highlighted above easier.

By working alternating hdc stitch rows with second back loop rows the pattern square creates a fantastic texture and look! See the picture below.
