Focusing Cloth Kit for the 8x10 View Camera only $39.95 You can use a bath towel as a focusing cloth, but it doesn't keep all the light out and you'll have a harder time seeing the image on the ground glass if you go that route. Our focusing cloth kits are minor, one evening sewing projects that yield a focusing cloth comparable to those costing much more. It is truely "light tight" with black on the inside, white on the outside, and small velcro tabs at the corners to hold it on the camera so you'll have both hands free to work the movements. There are even velcro tabs to hold it together under your chin so light doesn't flood up from underneath. This is a better solution than the cloths with weighted corners... they hang straight down and let light sneak up from underneath.
