We have a large Oval glass door window, and decided that we lose some privacy whenever someone comes to the door, And wanted a way to hang a nice curtain without drilling a hole in our beautiful door. I made a light weight lace curtain and purchased a small thin rod bought
Command Designer Large Hooks and hung them on my door to hang my curtains with. It's is PERFECT! My door has no unwanted holes, they are strong enough to support the rod and the curtains and we have the privacy we wanted. And easily just lift the rod off the hooks when we want that extra light.
