We love Barbies! One afternoon, we turned an old diaper box into a Barbie bathroom! It was pretty simple to put together, but did take a little time. We cut a door and window in the side of a box and wrapped the inside with butcher paper. I used old wrapping paper to line the inside and white copy paper for the floor and ceiling. Lots of tape and glue hold it all in place. Lots of fun pretend play!
