I have been doing this ever since I was a young boy, but when the bar of soap in the shower gets thin, I like to take a new bar of soap and "stick" the thin piece to it, thereby never having any soap go to waste.
You just kind of take the two pieces and squeeze them together, then you lather some soap and spread it around the seems of the two pieces. When that drys it acts like paste and keeps the two pieces stuck together.
