I know it's been done but I could not think of a more perfect treatment for an odd little section of wall behind my desk!
The whole thing probably cost me $6.00 because I already had fabric on hand. If you would like to re-create this yourself - simply purchase these super cheap embroidery hoops from your local craft/ fabric store and frame up your favorite fabrics. I went a step further and embellished a couple of mine with my felt flowers. It's personalized, fun and fits in that awkward space without feeling cluttered.
