The biggest thing I always see talked about in book communities is how people decorate their kindles.
It’s usually:
I don’t want to put the stickers on my kindle because I don’t want to ruin it.
or:
I put them in but didn’t stick them and they slide all over the place
I’ve found a solution: clear, reversed stickers. You stick them to your clear kindle case. You can read them from the outside, but not damage your kindle. And if you change your mind, the kindle case is easier to replace!
