Here's a dress I made for Kaylee (about a 3T, so she won't be wearing it for a while), and a closeup of the fabric's pattern if you're really interested.
This is not so much a "craft" as a fun idea I stole from a friend! I bought a huge pumpkin with the intention of putting Kaylee in it for some photos. She was very cooperative, despite sitting in pumpkin slime (actually I put her in a plastic grocery bag before putting her in the pumpkin to cut down on the de-gooping later).
