I am ready to try that method, or any other for that matter...any ideas on how I could go about it without 'wasting' 8 - 7 x 17 pieces of film at $4-$5 a crack? I thought about cutting the film into 8 strips and loading it into the flap end and exposing it to sunlight to see if I get the same problem? someone mentioned perhaps loading a sheet of paper cut in strips? Would this work? Thanks for all your suggestions.
