These guys are so easy to make I can hardly call it a pattern. This is such a great way to use up all those really small balls of yarn. Even the smallest pieces can be used to embroider the facial features or make the topknot. A lot of charities that deal with children take small gifts like these for the kids so make a bunch and donate them.
These are made with worsted weight yarn and a G hook. If you are making more than one stripe with the same yarn do not cut yarn after each round but carry it inside the worm and pick it up again at the next color change. This decreases the amount of ends you need to work in. When to change color is up to you, but if you like the hat look of the middle two change color after third row.

Embroider facial features
Topknot: (optional) Use 2 - 4 strands of yarn and attach to top of head as if you were making fringe, trim to the length you would like it and separate strands to fluff them up.
