I found these packs of gears in the jewelry making department at Michael's Crafts.
It turns out that the larger size gears in the set, lend themselves very well to being strung on a ribbon.
A longer string of these, would make a good replacement for traditional tinsel.
I made a wreath shaped ornament out of this string, though. I made a base with a hanging loop out of floral wire (wrapping the wire around a large pillar candle to get the size circle I wanted). I then threaded the gears onto wired ribbon. I Super Glued the string of gears onto the wire circle and tied the ribbon into a bow.
