My problem is that, yes, there's what I need in my stash, EXCEPT... and here comes another batch to "help fill in" the pattern, or add borders, or makes a perfect binding. No doubt about it; stacking the stash must go.
Am thinking of cutting foam-core to size and winding onto that. It was used at the print shop for mounting oversized posters and such. Again, a tip from another quilter. Dunno what I'd do with 100 comic book backing boards if they didn't please me.
