Displaying at a festival

I am entering an art festival this coming summer and a studio tour in the spring. I noticed last year when I went to these exhibitions that most of the artists had made their displays in which their art hung - to fit in a 10 x 10 space. Does anyone have suggestions in how to either make a display or where I can at least buy one? It would have to be able to support my artwork on both sides for hanging.
