I hang my design wall from picture hangers. They hold way more than the weight of the design wall and when not in use I either leave them up on the wall or take them out. All they leave is a very small hole which is barely noticeable and they are up so high you'd really have to know what you're looking for to see them. My sewing room is also used as a guest room. I use a small step stool to reach the top but I'm short.
