How do you give those over-sized hankens the same 
care that you can to a standard sized cel?
I want to eventually frame a hanken that I have, 
but until then where can I find a "cel bag" or 
container big enough? It's size is 15 x 17 
inches, and the largest cel bags that I have seen 
only go up to 14 x 17.
Any suggestions? 
Thanks,
E
