I'm going to say something different. You can buy bundles of FuzziBunz (in bundles of 6 or 12) and it comes out to be like $12 or so per diaper. There are some websites such as cottonbabies.com that send a free insert for each diaper as well.
When I wash them I do a cold rinse, then wash on hot w/a small amount of detergent or dish soap, then rinse twice on cold. I dry them in the dryer, but if i had a clothesline and some sun, I'd put them out to dry.
