Never know what to do with all those bits & pieces of leftover soap? You can purchase a mesh bag at your local department store like Walmart. (in the isle with body creams & bath accessories). As you collect these little pieces that you normally throw away just add them to the mesh bag. I also keep the small soap bars that you get in hotels. After you open the plastic on the drinking cups save the plastic & then when you are ready to check out just pop those "almost new" opened soaps in the plastic bag & store in your suitcase. Add them to the mesh bag of soap when you get home. Before you know it you will have a full bag. Hang on your shower handle & use. You will rarely have to buy soap again. As the bag gets wet it will lather up & the soap will melt together plus you get the added benefit of using the mesh for exfoliating while you wash.
