Last-Minute Christmas Project: Flowered Hats

I have 3 babysitters who watch my kids after school. They rotate who watches them. Two are girls, and we decided I would knit them hats. I ordered some Palette Yarn from Knit Picks and am going to start on it... in time to finish it before Christmas. Brynn is getting purple and Sydni is getting red.  I may buy some felt to line the hat with; I haven't decided yet.
