For this weekend’s show I am trying a couple ventilated shelf sections (about 18" high) for a theme display of a few small pouches & key chains & small stuff, and made my own “s” hooks yesterday from acrylic & med ply. I just used scrap leather to make the hinge–if needed I can tack to the table w/ a screw. But I had to give up on my idea of redoing my wrist band display for this show w/ more of these–ran out of time to make it work. (I can send a pic of this if you want!)
For many years I have used a tri-fold room screen I got at World Market–metal frame with a few horizontal rods, each section broke into 2 pieces, and a canvas cloth for each section–not as cumbersome as gridwall, and nice way to get hanging space & a neutral background.
But how heavy/large the items you are trying to display will drive what works.
I’ve seen cute displays using wooden ladders and shelves.
