I'm not but that is definitely relevant to my interests! I've had this idea kicking around in my head of starting a sticker library. I'd take a big binder full of sticker paper and put all my spare stickers in there, and take it with me to social/club events so other people could look through, find something they like, and leave stickers they don't have a place for.
But in short, maybe a book of sticker paper? I just recently learned they exist when I saw this one from Camp Mustelid.
