Rollout Wallpaper
Ideally, your apartment decor suggests a carefully cultivated, refined-yet-well-hung personality. The naked walls it came with, however, suggest "Wait 'til I hang up my Iron Maiden posters!" Steez up your walls, with Rollout.
If you're particularly creative, provide Roll with your own high-res design for printing. If you're not remotely creative, you can also select from around 15 rotating "stock" papers designed by contributing artists -- because you'll only be mistaken for well hung when your walls dangle someone else's steez.
