I ordered these cat meme stickers. And as I wanted to not use them and use them simultaneously, I came up with the idea of inserting them into a foil that I insert into an outer layer foil:
And adding tiny bits of sticky tape on the backside of each sticker and attach it to the inner foil layer:
Now I have used them without using the sticky sides of the stickers. So if I want to use these stickers for the intended (very serious) purpose, I can still use their yet unused original sticky side.
Also: Isn't that a fine selection of cat memes?
Only the best of the best cat meme stickers found their way into/onto that cringe sheet of foil to brighten up my - or your - or whoever's day.
