Double Treble: Yarn over your hook three times, then insert the hook into the stitch where you want to place the stitch. Yarn over and pull up a loop (you’ll have five loops on your hook). Yarn over and pull through the first two loops (you’ll have four loops remaining), yarn over and pull through the next two loops (three loops left), yarn over and pull through two more loops (two loops left), and finally, yarn over and pull through the last two loops on your hook to complete the stitch.

Pattern Notes

• The Granny Square pattern is written using two Colors: Color A (Rnds 1, 3, & 4) and Color B (Rnds 2 & 5). To use more colors, substitute Color A in Rnds 3 & 4 for Colors C & D.
• To make the Body of the Blanket, chain an even number of stitches for the width, then follow the blanket instructions until you reach the desired height. You can crochet this in a solid color or switch between colors.
• How to Change Colors: On the last stitch in the last group, or at the end of a row, work the last YO in the new color and drop the previous color to the wrong side of the work.
• This Pattern Uses Standard US Terminology.

Repeat from * all the way around the edges of the Blanket, working one st per every sc row, and 2 sts per dc row on the long sides (one st in each st of the short sides), and working a ch 1 and another st on the corner edges, join.
