I must say, it was super easy, and did not require rolling and rubberbanding of the individual diapers. Just my kind of DIY project! If you don't have time to make your own diaper cake, I suggest you check out eDiaperCakes.com, a mom-owned business that hand makes adorable diaper cakes in tons of color combinations. Prices range from $50 to a little over $100, and they even offer cakes with a book theme, which I love. Plus, shipping is only $5.
And you don't even have to tell anyone you didn't make it yourself!
