You need to see what he is talking about. At our museum we have some 'screens' that are made to hang art / pictures on. I've used them to hang quilts, but since they are only about 6' tall, I have to drape the quilt over the top which loses about 12 to 15 inches of the quilt for frontal viewing. Also, some convention halls have had quilt shows and have their own hanging methods......so, depending on what he can provide, you can either use the clips mentioned earlier or perhaps some magnetic clips that you can purchase at Staples. Lots of options on what they have so check it out early and you will figure out something appropriate.
