I don't know anything about makeovers for dolls, but I can tell you why you didn't find any Stampin Up products. They aren't sold in stores, but through home sales - kind of like Tupperware, but a lot more fun. I went to a party once, just because I was trying to be nice, but I had a blast. They carry the nicest rubber stamps and you actually get to make something beautiful to take home. You can check them out at their website and I have also seen their products for sale on ebay.

Good Luck!
