Jan 7, 2018 at 23:50 comment added Cindy Skillman If you can keep the clearbag surface from touching the pastel-painted surface, the clearbags should work. Touching the surface can smear it. Even if you've done your pastel on sanded paper or velour, this can still happen. In addition, condensation can form under the glass/plastic and damage the painting. That's why watercolor paintings need to be matted (unless you varnish them). For pastel though, ideally not even the matte should be allowed to touch the surface.
