Original base pattern: here.
See the first slouchy beanie I made from this pattern: here (puff stitch).
See the second one I made: here (shell stitch).
This hat will be available at the craft show (three and a half weeks! Agk, I gotta get makin' stuff!). I'm thinking it's more masculine than feminine, but what do I know? I did make it to be for a boy.
Ribbing: 4.00mm hook
First row: 4.00mm hook, hdc
Second row: 5.00mm hook, hdc in back loop only, 2 hdc (back loop) after every 4 hdc.
