I'm going to have my wife make a me a dark-cloth for use with my 4x5 cameras...monorail and to a lesser extent, speed graphic. I have never had a proper dark cloth before so I thought maybe you could give me some pointers on what makes a good one, that way I don't have to make a prototype before I get it right. I'm thinking white on the outside, black on the inside, with velcro tabs for wrapping around the camera's back standard, and maybe some pockets or weights sewn in the corners? What do you think? Does anyone have any patterns?
