As I've been busily rebuilding part of my site and handling 
my cels way more than I should, I suddenly noticed some of 
my cels with the staples on them. Should I remove these? There's 
something about cel warping when stapled. But I want the layers 
lined up perfectly, too. Tape? But I can't stand tape, unless 
it's the photographic archival stuff that doesn't yellow and is 
very expensive. Ideas? OK to leave in? Or am I being paranoid? 
(they're on a couple of my valuable cels, too)
