There are many ways to add colorful designs to your homemade soaps. We will discuss using the cold process soap making method to make soaps with intriguing designs.To make tri color soap with nice triangular designs, first make one third of your base recipe to pour into your standard block soap mold. Once the base has traced, add colorant of your choice, then prop your mold at an angle so that when you pour your base into your mold it will fill only one corner of your mold instead of the whole bottom. Now carefully cover your mold with a towel until your soap has gone through the saponification process and has cooled into soap. This will make a triangle block of soap that will sit off to the side of your regular bar, making a nice design.

First, make a plain white base to fill your mold, and then remove a cup or two from your batch. Add colorant to the cup of mixture, and then pour this into a cake-decorating bag. Use this mixture to write colorful designs onto the bottom of your mold.Once you have spooned a few inches over your writings, then you can carefully pour the rest of your soap into your mold (do this in one corner so if your writing is disturbed only one section will be messed up), let this set for 24 to 48 hours. Unmold and cut into bars. When you unmold your soap, the bottoms will have your designs permanently embedded into your bars of soap. This is yet another intriguing method used to decorate your soaps.
