I hated the fact that I had to put holes in my walls to hang my quilts, particularly as when I wanted to change to a different quilt I could end up making more holes. I have now found that 3M Command Strips Hooks solve the problem. They stick to the wall and are easily removed without any damage and they make loads of different sizes to hold various weights. I mainly use their utensil hooks and put one on each side of my quilt to hold the wooden dowel that I have put through my hanging sleeve.
I also use a variety of their hooks on the wall of my sewing room to hang scissors, cutting boards, rulers etc, etc.
I assume these are available in most countries; in the UK they are in all the DIY stores and at
