The large “Mylar” balloons I purchased didn’t come with any weights or anything to help keep them in place. Once I had them home I decided to attach them to the arms of the family room futon. Rather then tying the ribbons, I decided to use the plastic bread bag clips. I looped the ribbon around the arm and back up towards the balloon. When the balloon was at the height I wanted it I simply clipped the ribbons all together. The clips are holding the balloons securely in place. The kids are able to unclip the ribbons and move the balloons to pieces of furniture or to different rooms as they please. I’m not sure if this would work in a breezy outdoor environment but they work great inside.
