What should I do with these book dust jackets?

Whenever I get a hardback book that comes with a dust jacket, I remove it and set it aside. They just get in my way while I’m reading, and afterward, I prefer the look of jacket-less books on my bookshelves.

There are quite a few of these things hanging around my house at this point. On the one hand, I feel too guilty to just throw them away, but on the other hand… what the heck can I do with them? Some have decent art or typography, others are pretty boring. Got any creative ideas, jellies?

Bonus question: Does anyone else do this with dust jackets, or am I just weird? Well, weirder.
