Cowl:
Sizes from Child to adult you will just need to adjust the starting chain and add 2. The +2 does NOT count as a stitch.

The starting stitch of 60 +2 is for a child. To make it for an adult you will want to start with a higher chain number and add 2.

I used worsted weight but it should work on any yarn as well as hook.

Stitches:
slip stitch
single crochet
double crochet
Front post double crochet
Back post double crochet
X-stitch.
