And I don't want to spend any money either... Well, maybe a buck or two.
I have a Wisner 7x17 with removale bellows. I want to make a bag bellows for it to fit my 165mm S.A. Any suggestions on "cheap-ass" materials to make this thing? I was thinking of the heavy film bags some film or paper come in, maybe? Doesn't have to be pretty. Just light tight.
