I decided to make Brooklynn a Barbie house. We still had lots of boxes from the move (which we are saving for our next move) and there is a surplus of extra wallpaper in one of the storage areas here (for this house).
This is our creation out of cardboard, tape and wallpaper. It's not super-sturdy...but hopefully it will last until our next move. Meanwhile, I'm on a hunt for a discounted Barbie house at a consignment sale or yard sale...those things are EXPENSIVE! Or maybe I'll just build one out of wood someday.
