What do you do with stickers that you collect?
Keep them on their original backing.
Stick them to something!
If you collect Pokemon stickers at all, do you try to keep them on their original backing? I have some that I've attached to my flats binder pages with loops of tape, still on their original backing... but I'm looking for a small trading card binder, and since none with Rattata/Raticate exclusively on the cover exist, I'm looking into making my own and then adorning the covers with a bunch of rat stickers I've amassed.
