Have you ever heard of a Soap Saver bag? 
These little bags are made with sisal. They are the perfect size to keep in your soap tray. All you need to do is add all those pesky soap ends that crumble at the end of a bar use. This will allow the soap to continue its use! Once you’ve added all your pieces to the bag, wet the bag and lavish your body. You will also notice that the lather from this bag is very strong as a bonus! Once you are done with you use/bar, throw it in the washing machine just like a cloth or a towel! Good for many uses!
