What do you do with your leftover yarn balls?

My Boho-Steampunk granny shawl made from all those leftover yarn balls I couldn't part with. Believe it or not, I still have enough leftovers to make another shawl. The only thing I didn't like about this particular shawl is weaving in all those ends. Next time, I will try the "German join" and save myself some time.
