Explain to me Terry Flats

[PumpkinZulu]

Okay, so I am SOOO over disposable nappies! Every time I change one I just cringe thinking about landfills etc. So I'm making the switch to cloth

Don't ask me why, but for some reason I'm much more drawn to Terry flat nappies instead of MCN's But I have no idea what's what with them, so please share with me your expertise and experiences.

Many questions: What do I need? I already have quite a few terry squares, but I want some more. I need those snappi things, where can I get them? Also covers, what are they like? Are they plastic backed or anything like that to help with leaks, or do they just look pretty? Best places to get them from? What the heck is PUL (keep seeing that term and have no idea)? How often do I need to change, every two hours or so? Dry pailing and a little squirt type thing, is that all I need washing wise? What do you wash them in, do you soak in nappy san or what?

Sorry for all the q's and cluelessness. I'm actually hugely excited to cloth nappy Can't wait Roger started! TIA

ETA also, do I need a liner or something or is just the flat enough?
