Take something you really love, a letter, envelope, photograph, a ticket stub. anything - to a printing place like Kinkos and have them blow it up for you to hang as art. An old recipe from my Grandma would be great for the kitchen.
this is our guest bed and the simple linens is nice. I like the stacked magazine nightstand but couldn't do it. The coordinating but unique frames reaching high up the wall is nice and would be easy to do.
