Diaper Stacker for the Newman Twins

I made my first Diaper Stacker today! I couldn't find a tutorial online that I liked, so I completely winged it and truthfully I think it turned out pretty awesome. Sorry about the wrinkles, I still need to press it.

A little closeup of the ribbon I used.
A peek at the inside. No diapers handy, so I used books. Removeable Fabric covered cardboard stabilizes the bottom.
A side view.
And a closeup of the ducks! I love ducks!
