I have no frame of reference to answer your actual question (the reason will be obvious in a moment), but you should really look into doing them with cloth diapers, too.
Should we be fortunate enough to have another baby, I'm SO making or getting one of those for the blessingway I'm going to throw for my own dang self (not happy with typical showers, plus I wouldn't want a "shower" for my second, anyway!).I'll make it if I have to, but I always want to expand the number of people from whom I could purchase them!
If interested and intrigued, you can see what's out there, in terms of cloth dipes, at places like kellyscloset.com (and google cloth diaper cakes for visuals of what's out there AND the cost).
Good luck!
oh gosh I think making a cloth diaper cake would be great... BUT its gonna run into alot of $ unless she does all prefolds... but I dont like prefolds I like AIO's.
