Okay, so not everyone knows what a diaper cake is. I know this because I told a friend I was bringing one to a baby shower and she innocently asked "How many does it feed?"
This is the only one I've made. They take a bit of time and a crap ton of rubber bands, but once you get going it is pretty easy even for a first timer. I did cheat a little by using a huge bottle of baby wash in the center (meaning I had fewer diapers to roll & secure.)
I used larger sized diapers (size 2 & 3) since I figured the gal would get plenty of the smaller sizes from other guests.
