My husband and I are headed to our first art fair next month. My husband is the artist and I'm his organizer. He is a screen printer and will be selling prints, some of which will be displayed on a table and some in a print rack. He would like to hang some of the framed prints up, but we're not sure the best way to do this. The booths at the fair will be separated by just curtain walls. What do you guys use to create sturdy "walls" to hang framed pictures. He's discussed setting up several easels and placing them around the booth, but I think having them hung up around the entire booth would draw more people in. Any suggestions for easy-to-move "walls"?
