I have taken a $10 cork board from Hobby Lobby and cut it into 5-3"X20" strips
Run a line across the wall around 8" from the top, putting the strips of cork on the line and straight pins through the cork into the sheet rock (without ruining the paint or rock)
You can hang a quilt or a flannel sheet on it for a design wall, It will hold quilted quilts to hide what you are working on.
