I thought the article was useful as an inspiration, a jolt to make you think about your display in a different way, that was less practical, more artistic.
Yes for a small table, there isn't much space for display elements, but I've seen some fabulous booths that are 10x10 or larger that have more grandiose displays, including some that had a giant prop....that use every bit of space from floor to ceiling to catch your eye.
I used to do window and floor displays for a major department store, as well as some small boutiques. My craftshow display is practical and boring in comparison, and I've been considering recently what elements I could add to catch the eye across a crowded room or outdoor event.
