In order to make the stikers reusable, I was thinking of mounting htem on card board. Now those sticker are pretty thin so even on card board they could be hard to manipulate.
So I thought of either sticking them on very thick card board. If they are heavier, they should not fly around.
Stick them on regular card board, and cut 1 mm around the sticker to enlarge it's size. Use it like that or mount it on ticker card board again.
My standard has been using layers of comic backing board. Using rubber cement dry mount method, it's two layers of the board plus paper or stickers or whatever and a rotary cutter. Makes a thick, non-flimsy Token.
