I am a beginer; I just started with cloth pads last November, and have so far made a grand total of 2 pads! I haven't even gotten to use cloth for a whole cycle yet (combination of irregularity, and being home), but I've done a lot of research, and I have a pretty good idea of what I like, and what I'll be making.
I'm a college student in America, and I'll probably sew all my pads by hand...unless I can find a very cheap sewing machine. I'm also limited as to what I can put in my pads, as I'm in a very small town, with a grand total of 3 fabric shops, one of which is a quilting store. List of things they don't have: pul, nylon, and hemp cloth that is more than 45% hemp. So most of what I make will be water-proofed with microfleece, and have several layers of flannel/towel, between 7 and 11 inches long.
I don't think this will get very big for me, as I am a student; I think rather it will be a source of pads for me, fun, and a little bit of side cash.
I do have a website, so once I get started, I'll post there, and also on ebay.
