There are several different ways to swirl. You can swirl in the pot, swirl in the mold and so on. Easiest way IMO and the way I learned is in the pot swirl. (this method is for CP~it's a little different for MP) what you do is when your CP comes to a light trace take about a cup of raw soap out, color and set aside. Fragrance your uncolored portion, then take the reserve colored cup and from high up put about 4-5 drops in the pot at different spots in the bowl. Take your spoon and give it one or two at the max stirs, then pour in your mold.. That will get you started for swirls, and the rest is just practice.. HTH It's just basic, but like I said, it's a start.
