One of my favorite things to do in design is to find ways to make the most of any space. When I couldn't paint or wallpaper...art and double stick tape became my best friend.
In one of my earliest Chicago apartment, where my friends refused to visit me due to the "questionable neighborhood---which now is dotted with million dollar studio condos, a Whole Foods, Pottery Barn, West Elm and small batch/artisanal beer and cheese shops, I covered a whole wall. Floor to ceiling--wall to wall, with pictures I had ripped out of magazines. It was my own personal funky wallpaper that was there to hide an even funkier looking wall.
Embrace the awkwardness of a space and make it your own.
