Flat Nappies - Prefold and Pad Nappies

Prefolds are flat rectangles of material folded very simply. No pinning or "Nappi Nippas" required, but waterproof wrap, preferably with velcro closure to hold material in place.
Pros: Very economical, simpler than traditional terries, quick to dry, can double as absorbent insert for pocket nappies
Cons: More fiddly than shaped cloth nappies, prefolds can 'slip' inside wrap
