I love to recycle so I had a lot of old cd's hanging around so my first installment of what can you do with...involves old cd's. I made a collage for my office at work. I just bought a canvas at Michaels, arranged the cd's and glued them on, punched out circular pictures and placed them in the center of the cd's. I think it turned out pretty cute. Very quick project and spices up those office walls.
