Here's something I'm working on right now. It's a Gryffindor fair isle bag. Right now I'm working on the strap. I got the pattern for it here: http://www.the-leaky-cauldron.org/features/crafts/knitting/housecrestfairislebag Plus that book in the background, Charmed Knits by Alison Hansel, is such a good project book for Harry Potter fans!
The reason I'm knitting this is I'm a Harry Potter nerd. I have been since the books first came out. I'm intending to use this bag when I got to see Deathly Hallows.
