DIY Picture Frames: Make your own picture frames for your DIY wall decor.  Pick up a random assortment of frames (like those hideous brass ones) at the thrift store for super cheap, remove the glass, then spray paint the frames all in the same color.  White or black looks really nice.  Add in your favorite collected stuff.  The paint gives all of the frames a uniform look, while the structure and design of each frame makes it look unique.
