Double crochet (dc)

 I'm working these double crochets over a row of single crochet. Once you've learned sc, everything else in crochet is very easy. To start a row of double crochet, chain 3, and wrap the yarn around the hook, before inserting hook into stitch of row below.

That chain 3 will count as a dc in most patterns, so unless you want to increase the number of stitches in the row, skip the first st and insert hook into next stitch.

 Wrap the hook around the hook (just like sc).

 Pull it through the stitch of row below. You have 3 loops on hook.

By making a longer chain and several rows, you can make a dishcloth. You decide how big the cloth will be by how long your chain is and how many rows you make.
