How to Make the Double Crochet Stitch
Double crochet is abbreviated in patterns as dc; in the United Kingdom, the stitch is called treble crochet. Use it to make garments, scarves, and hats, but you will also see it show up in patterns for making almost anything you can imagine. Combine this stitch with others to make lots of patterns and projects, such as shell stitch, ripple stitch, and granny squares, all of which you can use to make larger afghans. The double crochet is twice the height of a single crochet stitch, which means projects work up faster than those with shorter iterations. Because double crochet is the same width, but taller, pieces worked in this stitch aren't as tight as those made with single crochet alone. The result is a soft, breathable crocheted fabric that is still fairly solid. Here's how to make it.
How to Work Double Crochet Stitch
To start the stitch, wrap the yarn over your hook. Next, on a starting chain, insert the hook into the fourth chain from the hook, or on regular rows of crochet, insert the hook through the V-shaped stitch.
Wrap the yarn over the hook again, then draw the yarn through the chain or stitch. You should have three loops on your hook. Wrap the yarn over the hook, then draw the yarn through two loops on the hook. You should have two loops on your hook. Wrap the yarn over the hook once more, then draw it through the last two loops. You should have one loop on the hook and a completed double crochet stitch.
Repeat the process, which, when shortened, goes like this: yarn over, insert hook, yarn over, draw up a loop, yarn over, draw through two loops, yarn over, draw through both loops. As you add rows of this stitch, work three chain stitches as a turning chain, which equals the height of a double crochet stitch.
