Ok - I've pushed pop-up shops in the past. Now I'm onto the pocket display concept. I've seen a few in recent travels. It kind of the same theory as glass display cases at the mall, which are located away from the shop itself to drive traffic from one side of the mall to the other.
For artists and crafters, this means you manage a display case at a well-traveled area such as an airport. The key is finding a willing sponsor, getting the floor space for free, keeping the display clean, with arts and crafts of the highest quality and having shop/gallery/contact info easy for potential customers to take away.
