We have a large stock of what-we-have-been-using 1/2" thick black foam pads, about 7" x 14", not quite Volara but something else, for placing under artworks when arranging and installing. We recently placed some natural linen-wrapped case decks on edge on these pads, but after removing them we noticed black markings on the linen. Besides that, we are endlessly having to double/triple stack 'em when frames have bell hangers or brackets on the bottom. I'd post a pic but I'm not particularly happy with what is our grandfathered-in pad of choice.

Please post descriptions and pictures of what you use, and any issues you might have (how to clean them, if they are bulky then how to store them, etc). Thanks!
