I'm going to my first show soon. I embroidered a bunch of euro pillow shams. I'm taking my wire cube racks. You know, the ones that are wire squares and you build them into cubes with plastic corner connectors.
The shams can store inside the cubes and hang over the front of 4 cubes. Then I just lift the flap and there's my stock! Overstock and bags go in bottom cubes.
