I love making amigurumi (Japanese crocheted stuffed toys). I made a cute little pumpkin during a craft day with some friends a couple of years ago and fell in love. The pumpkin was on my desk at work last year during the fall, but I decided in the winter that I needed something new. This froggy friend is the perfect desk companion (although he has since been replaced, a topic for another post).
