I used to keep my earrings on their racks between shows, then tape a bag over the rack. Earrings would fall off the racks, get caught in each other and generally make a mess.
This year I bought packages of perforated business cards at the dollar store, drilled holes in them, punched them out and folded them. Then I hung one pair to each card and put the carded earrings, 20 pairs to a baggie. Voila! Less wear and tear on everything.
It makes setting up the rack and clearing it a little more time consuming but not as bad as you’d think. And when a pair sells, they go onto a card and into a little poly bag. Next year I’ll use branded earring cards for this.
