IKEA chopping boards with velcro strips.
My buddy button slips away and sinks into my Roho bed so I can’t click it.
Velcro it to a stable, portable surface.
Cut a strip of fuzzy velcro and stick it the board.
Cut a small round piece of grippy velcro and stick it to the buddy button
So quick, cheap and simple! Another related make is Sugru Fingers
