Circles. Cold process soap making with recipe and essential oil blend. 

Love how this turned out!!! Your videos are so soothing

Very nice! I've seen older videos where people do a similar design by putting pvc piping in the base soap and pulling the pvc out after saponification to leave voids. Then, filling the voids with fresh soap batter. Your method seems easier.

So beautiful!!!! Thanks for sharing. Where did you purchase your planer from if you don’t mind me asking.
