I don't have kids. But if I did, I would be making this right now. Check out the tutorial by Stacy at Hart + Sew. It seems like a perfect travel toy.
I love the detail in each of the interchangeable backgrounds. I love that the floor lifts up to provide storage for doll clothes underneath. I think it's perfect for a little girl, but I think it would be pretty easy to adapt this for a boy as well. Perhaps interchangeable floors with different race tracks for toy cars. Maybe different jungle and desert backgrounds for dinosaurs to battle it out in. OK friends, someone needs to start with the baby making pronto so I can start making one of these things.
