I did the same thing when making a clothes closet for GD # 1. I used a dowel, though, for the clothes rod. I made all 3 GD's matching doll gowns and matching night gowns. I told them to save the things for when they had daughters.

I took a medium sized flat tote and made it like a bed..complete with mattress, pillow, pillowcase, sheets and of course a quilt! When the lid is taken off (which is the base for the mattress) there is storage!

Right now i have three large bins full of dolls, clothes and accessories. I guess i need a 5 shelf bookcase. Dear almost gd has two dolls and lots of clothes, but is only about 4' tall, so I'd have to include stairs. Lol! Maybe make her two of them. It's an idea! Hmmmm... There are some fun clothes on the " lives and loves of 18" dolls, and we'd love to see what everyone has made! Crazy about 18" dolls and trying to instill that love in my dgds !
