As I've mentioned before, I like to use Tim Holtz Sprocket Gears in my jewelry. I've done pieces for myself and for some of my friends for birthday presents. Here are some more examples for your viewing pleasure. I wore my necklace and bracelet to the Texas Beader's Retreat in January and they were a huge hit. I bet you couldn't find any of these gears at any of the area Michaels stores after the retreat.
