I recently saw a tile artist using these little blocks to display their handpainted tiles and thought it was a good way to display one of my canvas panel abstracts. A neat and cheap alternative to having them framed. It gives you lots of options for display and avoids a nail in the wall, plus you can move them around as you please. I made these out of Alder and routed a groove to accept the RayMar panels, which are rigid enough to stand without warping.
If you purchase a panel and would like one of these, let me know and I'll throw it in on the deal.
