Don’t throw away that scrap of soap! Passed on from my grandmother who never wasted anything because she knew what it was like to live without, this tip lets you use up every last bit of your bar of soap.
When your soap is down to a sliver, soften it in some water and then lay it on top of your new bar. Gently press them together to bind the two pieces then let them sit overnight. By your next shower, they will have melded together into a single usable bar!
