paint or wallpaper alternatives?

paint or wallpaper alternatives?

So, I have a hankering to paint / put up wallpaper, but I might not be able to get it approved by my landlord (it will take some sweet-talking, or perhaps several batches of cupcakes...). I'm wondering if any of you have alternatives to painting and/or wallpaper, or know of removable wallpaper solutions. I'd really like some color to finally bring my spaces together. And, just so this is not a text-only post, here's my new bedding: New Bedding. You can take a "tour" of my apartment here (note: I need to update this a bit since I've changed some things, especially in my room). Thank you in advance!
