Single crochet, sc (US) / Double crochet , dc (UK)
In this DROPS video we show you how a double crochet (dc). In the first row, we show how to work the dc in a ch-stitch. On the second row we work in both loops. The dc is usually worked under both loops from a previous row, but you can also work in the front or back loop only, which will give a stripy/textured look.
Work a dc as follows: Insert the hook in stitch. Wind the yarn around the hook and pull it through, leaving two loops on your hook. Wind the yarn around the hook again and pull it through both loops.
