Won't the cel stick to the bag?  I was nervous
about leaving my cels in the cel bag and ended up
throwing all of them away.  I use that scrap book
at micheals with the white/colorless paper
backings.  It seems to work well and I didn't
notice any scratches.  Would you find the
"scratches" on the back where the paint is or on
the front of the cel?  Or does it REALLY matter
since all cels have been handled before and
nothing is really perfect when it comes to art?
