I was wondering how most of you store your cels.  
Do most of you use cel books?  Cel bags?  Do you 
usually store your cels with their matching 
backgrounds/pencils sketches (if applicable)?

I like to look at my cels occasionally so I tend 
to keep my cels with their backgrounds and 
drawings (I like the white as a background), but 
I'm finding out that some of my cels have started 
to stick to their backgrounds.  I don't really 
care all that much with my backgrounds because I 
don't intend on ever separating them, but it sort 
of bothers me with the sketches.  So what I've 
begun doing is putting just the cel into the bag, 
and the drawing separate.

Another question:  why do some cels seem to stick 
more than others?  I have a few Laputa cels that 
don't stick at all, whereas some of my newer ones 
stick right away.  Does it have something to do 
with age?  Do cels ever lose the ability to 
stick? 

Any help would be appreciated.
