This is the second hat in a row that I've published with a rolled brim. An easy-to-make rolled brim at that.
The roll in this pattern -- Pixie(ish) -- and in its recent predecessor -- Pop-Dots -- is created by using a crochet hook that's 1 mm bigger than the gauge hook. In Pixie(ish), I used a 5mm hook for the hat body and a 6mm hook for the brim.
My friend Lois showed me this cool technique. You can also create a rolled brim in crochet with front-post single crochet stitches for a slightly different look.
Just published, Pixie(ish) is available on Ravelry and Etsy with a 50 percent discount until Dec. 31. On Ravelry, use the code PIXIE to get the discount.
