The Classic Cuffed Hat by Purl Soho: This was my favorite of all (and Samson's too apparently)! Easy, quick, and very cute. I've gotten a million compliments on this yellow hat, and just finished my THIRD for a holiday gift this morning. (Important: This!)
Effortless Beanie by Yarnspirations
Beginner's Favorite Knitted Hat by Red Heart Yarn: I wish I had made this one a little longer, but I got paranoid about running out of yarn. Kristie has claimed it as her own (and she is rocking it).
