Knitting: Beanie, Toque
This hat can be worn four different ways. You can fold the brim in half to get a slouchy hat, or all the way to get a fitted hat and you can turn it either side out.
Crochet: Coaster
Any worsted weight yarn will work. I used acrylic and superwash to get colours I liked and for washability, but wool or cotton would work as well.
