Baby Shower Gift: Diaper Cake

Okay, I'll admit this is not a pure fiber craft project, but bear with me! There are a number of babies being welcomed into families I know this summer. My cousin in Maine is due with her first at the end of August, and had a baby shower this weekend. I like to give useful gifts, and we can only wrap babies in so many blankets. Diapers, however, are almost always needed.
