Layered Handmade Soap Kit and Tutorial from The Soap Queen that uses a similiar project. So if you are like I was, then I would recommend trying their project. So basically, layered soap is a classic design. Depending on the technique, creating layers can be easy or difficult, according to The Soap Queen. This recipe is made using a technique known as "spoon plop". It is when the soap is plopped into the mold, which is very easy to do and it creates a completely different bar each time.
