So one could theoretically "gelatin back" a modern folded 1sh and have it returned with no back? This sounds awesome. I've never heard of this until now.
I'll be honest, my main complaint with linenbacking isn't the fold/stain removal, or archiving, it's the heavy ass piece of annoying linen stuck to the back of what should be a piece of paper.
I'd consider sending my folded Jaws (and a few others) to have this done rather than searching for rolled upgrades.
Ballpark cost for a 1sh?
