Ok, so I've been looking at info for the past hour of so.. things are vaguely beginning to make sense, but it could be another 2 weeks of solid research before I have any real idea of what to do. At the moment I'm just going to focus on a pattern and will probably just do a different project with the rest of my class time.

What is the difference between a pocket nappy and an all-in-2?

if I've got it right the pocket nappy has a waterproof PUL layer, an inner stay dry layer with a slit at the back, and you stuff them with pads of moisture absorbing material such as bamboo?

The all in 2 - does that have a waterproof PUL layer, then an absorbing layer, than the stay dry layer with snaps so you snap in extra pads as needed? How do you make the extra pads, would you also do them as a moisture absorbing core, wrapped in a stay dry layer with snaps on one side? Does that mean you can only have one booster in at a time, compared to a pocket where as long as you can get it in the pocket you potential to stuff it with absorbing material is endless?

Assuming you made them with the same material, which would be better at aborbing - a pocket or an all-in-2?

I'm planning on making a lot, so I'm not so concerned about drying time. If you fold over a booster (do you mean for an all-in-2 or for a pocket or for both), then do they still stay in place?

I can't knit at all, and I think I have to go pocket or all-in-2 because DH will only just cope with something that looks like a disposable TBH.

I have a press stud kit from spotlight, which should be able to go through 1 layer fine, but I guess if you are making an all-in02 you only have to attach them to the pad and the suede/microfleece layer anyway?

And what is the difference between press studs and snaps?
