I had some avocado cucumber melt and pour base and some olive oil soap base. I made two small thin batches of avocado cucumber soap. It was cloudy. I made them pink and blue. Cut them up into little squares. I then made enough olive oil soap to cover the bottom of my container/mold. I tinted it light purple and made it smell like pink sugar. I poked a few of the blocks in it. I would then do a few layers of more olive oil soap and put a few more blocks in it.
The most important part of layering I learned is to spray alcohol. Once you pour the soap, spray alcohol to pop the bubbles. Before you can add another layer, you need to spray with alcohol again. I read that if you don't have alcohol sprayed, that the layers won't stick and they may come apart.
