A few years ago I hung a pirate fabric all over my ceiling and black sheets to cover my walls. I used 3M removable hooks to hang everything. When my husband and I removed the 3M "removable hooks" part of our drywall came off with it. We tried everything to not get the ceiling/wall to come off with the hooks. I'm getting ready to hang decor again and need suggestions on how to hang decorations WITHOUT causing damage to my walls (I had to pay a drywall guy $$$ to come repair my ceiling/walls - YIKES!) Obviously I need something strong enough to hold weight. What does everyone use??? Any help would be MUCH appreciated!
