While I'm obsessed with the slouchy version of this hat, and have made it several times for a variety of charities, this pattern is perfect for a variety of knitterly loves. You can make just an ear warmer, you can make a fitted beanie, or you can make my favorite slouch hat, all by using the same pattern.
Written for wool yarn, any bulky weight yarn can be used to make this hat gorgeously, and I've made it with acrylics in the past, always with good results. This means you can make this hat to donate to oncology centers and hospitals as well, where washable and allergy-free are required!
