Knitting with Double Pointed Needles is Fun

Currently knitting another water bottle coozie. It is red this time. I am an AFL fan. The name of the team I currently follow is the Jacksonville Sharks and their colors are red and black. I definitely want to felt a shark or a sharks fin on the coozie. If anybody out there has any tips / suggestions on how to do this, please don't hesitate to leave me a comment. I need to hurry and finish this coozie because I have another baby blanket to knit for a boy who is due in October.
