Getting Creative with Leftover Soap Pieces
Let's say you want to get creative. Pull out your essential or scented oils and your food colorings. The oils can be purchased very cheaply at dollar stores or discount drug stores.
Add about 10 drops of essential or scented oil to your soap base, and stir until well mixed. This may seem like a lot of scent, but some of it will evaporate in the drying process.
Decide what color you want your soap to be. Regular food coloring will work fine to make lighter colors, but for darker colors, you may need to use professional icing and food color paste from the craft store. With just a couple of dips of a toothpick, you can get a lovely, darker color than with regular food coloring. NOTE: Although these professional color pastes are non-toxic, they may cause the soap to run when used.
If doing a swirl design, you will wait until the soap base is in the molds, then you simply drop a drop or two onto the soap base, and swirl with a toothpick or piece of large spaghetti until you get the desired effect.
Once you have colored your leftover soap mixture, you can either leave it in the bar holder to dry, or pour it into tiny guest soap molds, which you can purchase at craft stores. These molds can look like candy molds, or can be hollow, two pieced molds with a hole in the top for pouring in the soap. Simply fill the mold with the recycled soap, let dry, and there you have some beautiful, scented guest soaps.
