Me (raising hand). OK, so I had a little help with the sewing from my wife. It wasn't too hard.

Regarding material, the big question is, do they need to be waterproof? You didn't mention what they will be used for. If they don't, simple uncoated nylon or lycra should work fine. If they do, there are lots of W/B fabrics to choose from. Check OWF at the top of this page. They sponsor the site and they sell the hardware too.
