I'm in the same boat as Asylum Steve in the belief that there are many things in photography that if you pay full price for it you're a sucker, because you can make comparable products for much less. Now that I've started shooting more wildlife, and I'm going to maine this week for a whole week of wildlife photography, I started to think back to an article I read. Imagine you are some sort of wildlife and you see this giant creature come towards you with a giant white thing, and point it straight at you. Would you be scared? The answer is of course, so I decided to make a camo cover. Costed about $2 total, a trip to joann fabrics, and a couple hours of work.
and the answer to your question is "yes, I know how to sew."
