Have you heard of the Convertabunz by BunzukeCloth Diapers? One product transforms into a prefold diaper, a fitted all-in-one, an insert, an AI2 and lots more. Watch this quick video and be amazed.
Bunzuke has released a very thorough pattern with instructions (which you can buy here), so you can now make your own Convertabunz to use yourself or to sell. (Be aware that you'll need a KAM table-top snap press along with some other items from KAMsnaps.com).
