Just keep trying different things. I've made a few that didn't turn out too bad. One I really liked I somehow screwed up on so I had to just delete it. For the camo's themselves, those are pretty simple, just have to paste any pattern or picture over the old one and save it properly and you're done. Doesn't always look the greatest but for a whole 2 minutes it takes to do it who cares. When you're done make sure I get to see a pic, maybe I could help improve it if you want? Or I could make one too once I see how you want it done exactly.
