This website has some cool free printables for Barbie. Cereal boxes and things like that, pizza boxes, shoe/hat templates, shopping bag templates, etc. And directions on how to make other stuff for Ba (Diy House Doll)
My daughter and I are building an Anti-doll dollhouse. That would be a doll house with dishes in the sink, pizza boxes on the living room floor, and a motor cycle engine being disassembled on the kitchen table.
