Diaper Cake Anyone?

I have to keep myself busy when everyone is away, usually with some kind of project. The office is having a surprise baby shower and the only requirement was to bring diapers and wipes as that's all they needed. I had a bunch of diapers left from Bossyboy but the package was already open. Since I didn't want to just give them the diapers as is, I took it upon myself to learn how to make those cute diaper cake centerpieces that I have seen around.
The cake is really quite easy to make and I think it turned out really cute. The ones I have seen are all decked out with baby toys but I like the plain look best.
I hope they like it.
