Have you seen this bookcase turned dollhouse? I found it while researching ideas for a little girl's room on Pinterest. It is from The Land of Nod, but I can't find it on their blog anywhere. It would be so easy to create this with an Ikea bookcase. I played Barbie's until I was about 12 years old....I would use books to create walls for rooms, and my sister and I would build our Barbie house maze out clear across the living room. We would have loved this house.
