My daughter was invited to the birthday party for a little girl she babysits. We went to Target for a small baby doll. I learned my lesson making these beds last fall, always buy the doll first. I made several but couldn't find babies small enough to fit, never mind that we had a million that size when my girls were small(er).
I based this on little doll bed purses I bought for my daughters at a craft fair before Easter many years ago. I know the concept is an old one. When I showed this to a good friend of mine she started gushing at the memory of her own doll bed when she was young.
