I just purchased a 12 inch Shirley Temple Doll for my wife and need to find the right stand for the doll ?

Personally, I keep my NIB dolls in their boxes, but if you want to buy a stand, I would go to a local craft store like Michael's, if you have one in your area, they usually have an assortment of sizes, you can take the doll (or just her measurements) with you to get the correct size.
