Hang some corsets and gloves above your bed frame for a vintage, yet modern look.
I don't know where to find these corsets, though. I'm guessing maybe a flea market?
Use travel magazines pages, or nature cut-outs as wall photos.
Make a collage of old picture frames and window blinds.
You can find really cheap, old picture frames at any flea market.
Oh, I can't wait to have my own place and start decorating!
