Here’s how I hang my Christmas starburst!! This is my fifth year I believe hanging these guys, and I still love them!!! I use two 3M Velcro strips on the back of the battery pack. To shorten them I just roll the cord around the pack. They usually stay put, I have had them fall off a couple times before though lol! Then when I need to change the batteries, I replace the Velcro strips. I hope you try them!
