I'm starting to plan a utility room darkroom in the basement. I don't want to build a permanent structure, so I did some research and came up with: blackout cloth, commando cloth and Duvetyne.

This is one specific product that looks promising. If anyone has a better fabric choice, let me know. http://www.rosebrand.com/product34/B...526%2bBlackout

The ceiling of the room is unfinished. So my plan is to attach the cloth with Velcro onto the wooden supports above. I'm not sure yet how I'll anchor the cloth to the floor. I've thought of Velcro, or using weights of some kind. For the door I expect a flap fixed with Velcro would work.

If anyone sees a flaw in the plan or has some advice. I'm all ears.

Thanks,
