Hi, Trying to help out a friend with no budget. He needs to build some flats. He's got some 4x8 steel tubing already welded up into frames for frats and just barely enough budget to buy muslin to cover them. However, he doesn't have the extra budget to buy luan to properly attach to the steel tubing first. Any ideas on how to attach muslin to steel tubing to make flats. Adhesive doesn't sound like a very good solution. With such a small surface area it seems to me sizing the muslin would pull it loose. Rivits on the back every 6" ? Maybe screw some 1x2 to the back to sandwich the muslin in between?
