What Happens When Felted Soap Is Used Up?

This is my fist felted soap that I made. I used it to test out my felted soap and it worked great! Here it is after all the soap is gone from the middle.

I decided to cut it open and show you what the inside looks like.

You can see the different layers of felt and they've all shrunk leaving a rather tiny space for the soap as it was used up.
There are still uses for the little pieces of wool.
It would still work well as a scrubbie, on dirty hands or dishes just with soap added now.
It could be used to protect jewelry when packing very light.
My pieces fit neatly on the ends of my fingers; they could be used to make cute finger puppets.
Do you have an idea for how to use the leftover felt? Please share it in the comments. :P
