One thing I've been wondering about. What's the problem with making an outer bellows out of the same cloth used to make dark cloths? It would likely cost a person the abilty to squeeze the bellows real tight so short lens would be a problem. But other then that?

Plenty of older cameras out there that aren't worth a new $200+ bellows but might be put back too work relatively easily. Obviously I'm missing something just not sure what-)) Basically the idea is an extension of throwing your dark cloth over the bellows while you take the photograph.
