"Short" Shotguns are great at removing "chatty Wooks" behind and the sides of you.
I actually made my own pair of windscreens. I was camping before a show (Moxy Fruvous, Donna the Buffalo at the Grape Jam) and realized I left my windscreens at home. I was in the middle of no where, and found a strip-mall with a Radio Shack in it. They didn't have any windscreens in stock, so I went next door to a dollar store, and bought 2 of those foam basketball sets that you hang on the back of your bedroom door. Next to the dollar store was a craft store. There I bought some fake fur, as I had recently used a pair of rycote softies. Using my pocket knife, and a needle and thread from an emergency kit, I made these by latern light the night before the show. They worked great at blocking the wind (I've used them a couple times) but may make the low end a little muddier. Still, for about $5, they're not too bad.
