As humans, we have two hands. But, every time you think two are enough, you need a third one. You can buy 3rd hand tools which is just a couple of clamps mounted on a bendable shaft of some kind. But being cheap, I decided to see what I could do with a few bits and pieces I had laying around the garage. I had a bag of plastic clamps I bought at Home Depot, some leftover aluminum clothes line wire, a few wooden clothes pins and gaffers tape. I was able to pot together a clamp in ten minutes that would hold a light flag or reflector or even a lightweight subject like a flower.
