Thanks Caro I've now put permanent ebay search on for prefolds. Found the hemp ones but at $8 each I am still hoping I can find the $3 variety somewhere.

Simone - prefolds are the next step up from a flat. They tend to have three panels - the middle one is thicker and more absorbent. Ozcloth has a good explanation of the different types of cloth nappies. It does take a bit to get your head around the vocab. Eventually it happens.
