I keep all of mine in Itoya books!  

Framing can get pricey cause I'd want to do many 
cels, but thats not the real reason why I don't 
do it.. I simply don't have the wall space.  Not 
even to properly display one!  I still live at 
home so I just have my bedroom to hold all my 
junk (and I collect a LOT OF STUFF!)  ^_^;  
Whenever I get on my own I plan on framing as 
many cels as I'd have room to hang.
