That whole psychedelic poster scheme you had in college went out of style, well, long before college. That those monstrosities still hang on your walls doesn’t bode well. Time to graduate to a new level of decor with wall stickers from Ferm Living. The easy-to-apply designs occupy lots of space, so they can serve as sole decoration for a room. For something that doesn’t scream “student budget,” try one of the nature motifs — like interlacing branches, hydrangeas, or sparrows. The super-tall shadow of a power line suits urban environments. Oh, and the fingerprint or fly-on-the-wall stickers (actual designs of houseflies) will definitely have you tripping out. In a more age-appropriate manner, of course.
