This particular diaper cake used about 150 diapers in both size 1 and 2. I used storebrand diapers for the center of the cake and premium diapers for the outside ring. All the items combined cost about $70.00 and you may not consider that frugal. If you were to purchase a diaper cake of this caliber from online or at a boutique you would be paying well over $100.00.
1 3 pack socks - $2.99
1 stuffed monkey - 4.99
1 pack of two pacifiers - $1.00
The cardboard "cake" plate I cut out of a cardboard box so that was free, the ribbons I used to tie the diapers and secure the ribbon was curling ribbon, and was purchased from Dollar Tree (Obviously for 1 dollar). I had the basic ideas for the cake and watched a few instuctional videos on youtube. I found the cake to be prettier when you put the items on the inside of the cake rather than hanging from the outside.
