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 or completed afghan.

The Stitches For a Crochet Rectangle

To crochet this rectangle, you will need to know how to puff stitch (puff) as well as single crochet (sc). The sc is a basic crochet stitch that is easy to master. You can take a look at the details of these stitches below and try them before you begin.

Crochet Stitches for Puff Rectangle Pattern

Puff Stitch (puff): 

  1. Yo, *insert a hook into the designated stitch and pull up a loop, repeat from * into the same stitch 3 times for a total of 7 loops on the hook
  2. Yo, pull through the 7 loops on the hook.

Single Crochet (sc):

  1. Insert hook from front to back in the second chain from the hook or designated stitch
  2. Bring the yarn over (YO) the hook and pull the yarn back through the chain (or stitch)  from back to front  (2 loops on hook).
  3. YO and pull through both loops on the hook.

The square pattern is created by crocheting a row of single crochet stitches followed by a row of two single crochets followed by a puff stitch. This combination of stitches creates a beautifully textured rectangle and the puff stitches add a nice volume to the design.

See the picture below to take a look at the stitches up close in this rectangle.

  • Keep track of your tension + gauge so that you get the 7″ x 9″ size requirement
  • Make sure your starting chain and first row are 7″ before you continue on. If it isn’t the correct size change hook sizes to get the accurate gauge or fix your tension.
