I have some pieces of sheet aluminum that I cut to be just larger than the stickers. I drilled a hole in the corner that fits a small carabiner, and then I can just clip it to something easily. I use this for duckies, sometimes it is clipped to the bag they are stored in, on the river, I clip them to the carry handles.
My buddy with raft puts them on his frame.
