Since I was trying many different types of diaper, I started playing with prefolds and a snappi as well. I can see why people love the old school diapering as well.
Once you master a couple of folds, you can even mix and match some of them to create a fit customized to your baby. I've been using a mix of jelly roll fold and bikini twist under a cover. This creates a trim diaper, and if I've done the jelly roll portion properly, it keeps the poop off the cover.
Prefolds are a very economical way to diaper your baby, but you do get what you pay for.
I was disappointed to find that Gerber prefolds are not 100% cotton. They have an absorbent "pad" sewn in the middle. They will work, but aren't as nice as 100% cotton prefolds.
I have some bamboo prefolds on order, so I'll talk about those later, once I've given them a good try.
