Hmmm.......What to do......

I made a bunch of various sized soap balls with left over soap. Now I have to think of a creative way of using them. Just tossing them into a batch of soap sounds too simplistic and ordinary. It would look pretty with the different colored circles in the sliced soap but I am going to try to think of something different. Any ideas? The larger balls to the left are all of the colors combined. Bet they will look really neat inside.
