This Jagged Crochet stitch looks awesome I just had to try a beanie too! You can make it a beanie or slouch hat! If you missed any of the patterns I made with this stitch then you can find the links below. This pattern shows for toddler to adult.

For this project you will need:

HOOK: 5 mm hook or size H hook for the US

YARN:  A skein of worsted weight yarn, 4 ply US, 10 ply AU

There is a video tutorial on the Jagged stitch on my YouTube page that you can find here
