As a FYI, if you use Pro Panels or similar fabric covered panels for art display I wanted give a plug for Harmon Hooks. They use Velcro patches and a riveted hook for each patch to support the art work. This is a lot faster than using drape hanging hooks and far less damaging to everything from the panels to the art, to your hands. They are very quick to set up and take down too.
A neighbor used these at a recent show and I was impressed with everything about them so ordered a bunch. These will save a lot of time during set up, as works sell or are re-positioned, and to remove after the show. They will also save me the need for most bandages and especially the need to wear work gloves when installing and removing.http://harmonhooks.com/
