Those Riddlesome Moleskine Stickers

If you're like me, you collect those little stickers that come with each Moleskine book. They're labeled "Quality Control" and they combine two aspects: color and design. I haven't kept track of which sticker comes with which type of book, but I have an awful lot of the little gridded ones, in green, orange and yellow. I have one or two of the other designs.

Stickers are fun. Who would throw them away? But the thing is, I don't know what they're for. I held onto them in a little ceramic teacup until I could decide on their function.

The first instinct was to simply lay them out on a piece of paper, organized by design, to have a large one-page collection of them, but I felt they should have a better purpose. My second idea was to use them to seal the backs of envelopes, and that would be sufficient but I still felt there was a reason for them I didn't perceive. In the back of my mind, something nagged that they should go on the books themselves.
