How Do I Make A New Bar Of Soap From The Ends Of Old Bars?

I have the ends of various old soap bars. Much of it expensive gift soaps. How do I melt ‘em down and squish ‘em together to make an new bar of soap?

How Do You Combine A Heap Of Little Endy Bits Of Soap Bars Together To Make Bigger More Usable Soap Bars?

I work with the Aged People in my community and have a Client who has been saving the small pieces of soap that are left over when the soap bar has been used for a while. He literally has a bucket full of it! He wants to find out how to combine all the pieces together to make larger bars. If anyone can help with simple directions I (and he…) would be very grateful.
