I am starting to know my film but the negatives I still need to print, or worth saving are piling. I used to save my negs in envelopes but discovered the paper gives a very fine dust to the negs. The photoshop has some of these special neg covers but I find them way to expensive. So how do you guys store your negatives. And is there a simple trick to cut straight? I don't like the idea of placing them on a table and put something straight on it and use a knife. (scratching/dust etc) but simple scissers are hard tools to get straight negs. Thanks for any suggestions in advance. cheers!
