Diagonal Square Filet Hat

This is my favorite hat that I have made so far. I was trying to think of some ideas for designs for my hats and I remembered a design from a crochet pattern book. It is a Filet design similar to th blanket in the earlier post, My First Crochet Projects. The pattern was filet squares in a diagonal line. The pink stripe was a neccesity rather than great design thought. At the time I had made this hat I had never used more than one color (I had not attempted to change colors yet), but I had to due to running out of the grey before the hat was complete.
