Here is a diaper cake that I made. It is super simple
but you can add all kinds of lotion, soap, and so on!
I spent $15. :)
You will need:
50-80 cloth or disposable diapers
(number of diapers depends on how many tiers you want)
A bag of rubber bands (various sizes)
16” Disposable cardboard platter. (found in party stores)
At least 8 feet of 1’ wide ribbon ( need more if cake is more than 3 tiers)
Clear adhesive tape
Decorating items ( pacifiers, bibs, toys , socks, etc.)
Decorative cake topper (stuffed animal or bottle filled with candy)
Roll diapers with tabs tucked in
Wrap rubber bands around each diaper roll.
Use rubber bands to create a bundle with the diapers
(may need inner & outer bundle for larger tiers)
Use ribbon or receiving blanket around the cake to cover rubber bands
Use the clear adhesive tape to attach the tiers to the platter
I took this how to from here.
They just did a better and much more simple job at explaining it! :)
