I actually bought a diaper pattern and modified it to make my own AIOs. My goddaughter is using them now and her parents love them. My SO and I plan on using them unless we go on long trips without access to our own washer. I just feel kinda guilty using someone else's wahser for my child's dirty diapers. We're even going to set up our second washer and dryer just for baby use.

I've debated on selling them online while I'm home with the baby but I'm not sure of the market...

Oh, the website that I got my pattern off of is www.newconceptions.com. It also has some great information about using cloth.
