I think this idea is adorable. Old suitcases have such personality and remind me of my childhood. Isn't this a great way to use those old (heavy) suitcases, and get everyday use out of them.

I am sure good looking old suitcases are now a hot commodity at flea markets and antique stores! Do you think I can find one big enough for my wild golden retriever?!
