I don't know about you, but I suck at color work. I am all for an easy, yet looks-difficult pattern that uses more than one color of yarn, and the Flying Colors Hat by Heather Dixon available in the Stitch Nation Collection 1 pamphlet by Debbie Stoller is perfect.
The fun Blister Stitch (demonstrated to me by my friend and knit guru Pam #2) makes for what looks like complex knit madness, but is indeed simple enough for the color challenged like myself.
Amazing stash buster as well! My version on Ravelry.
