Hey, I was wondering if anyone knows how to frame charcoal drawings without it smudging, as it is very delicate medium. The problem is that most of the videos I find online are for small scale charcoal drawings, and the one that I want to frame isn't. I posted above what I want to frame, it's about 70 inches length wise (top to bottom). I did it a few months ago and It's just been sitting here on my desk, I'm worried that sooner or later I might brush my hand or elbow against it and ruin it :/
