Amigurumi are mostly single crochet.
Sometimes we need some slightly taller stitches (like on the convex side of a bendy piece) so we use half double crochet.
And sometimes we need something even taller, so we use double crochet.
Here’s how to do it.
See how easy that is?
And how much taller it is than single crochet?
That height also makes it a little drapier, so it’s one of my favorite stitches to use for scarves. It’s even drapier if I go up a hook size. 🙂
