I'm in the process of making a 84" x 96" design wall for one side of my quilting room. I'm making the board out of 3/4"foam board covered with craft felt. I don't want to make holes in the felt when I screw the board to the wall so I decided that I'd like to attach it to the top of my wall with picture hangers or a close to the wall rod or something. Any suggestions? I'm using the washable felt so that when it gets dusty I can take it off and throw it in the washer/dryer.
