S.T.
I haven't messed with making them, but you can google free diaper pattern. Here's one such link. http://www.zany-zebra.com/free-cloth-diaper-patterns.shtml
some moms use PUL which is a fabric that has plastic fused to it. That way you need no cover. It's expensive though.
I have bought diapers on www.craigslist.org and free on www.freecycle.org and free or purchase from www.diaperswappers.com. there's an ad on the last site for a free diaper ministry- if you qualify they will loan you diapers and wipes and covers for the cost of shipping.
I have NEVER had a diaper leak. I'll use flats or fitteds with the velcro or snap covers. I have covers like whisper wraps and the ones from Mother Ease and fitteds from Mother Ease and Kooshies. I also have some that don't need covers from Happy Heiney. They are REALLY sweet but expensive...
Feel free to PM about CD!
