Gripping and lifting bags with hand impairments is very difficult. Wrapping a small stone or golf ball in the rim of the bag and then tying it off with a string or rubber band creates a secure handle to lift the bag without squeezing the flexible material with the fingers.
Any bag, rock or golf ball, and a rubber band.
Take the edge of the bag, where you would normally grab to pick it up, and wrap the outside of the bag around the rock or golf ball.
Wrap a rubber band around the bottom of the newly made handle to keep the rock or ball inside.
Now one can more easily pick up the bag by just using the handle.
