I also love things that are versatile. The above figurines were created from polymer clay, a medium with numerous uses.
Wood grain buttons from etsy seller blarneyyarn
you could make cute little stitch markers in any shape you want.:

Or you could make accessories for your Amigurumi:
Indian Jones amigurumi and accessories from etsy seller GeekCentralStation
Accessories for Link (from Legends of Zelda) as seen on Geek Central's blog
