I am in love with these unique and inexpensive stencils from Stencil1. Cheaper than wallpaper, you can create interesting patterns, or just stencil one to your wall for a focal point - wonderful!
Birds on Wires, $12.99. I would love this for my own bedroom!
Moroccan Petal, $12.99. This would be wonderful in a bright kitchen or breakfast nook!
Typewriter, $10.99. Can you imagine this one adorning the walls of an office? Too cute!
