POT SWIRL
One of my favorite techniques is the pot swirl technique. Different colored soap glues are emptied one after the other into a container and then the soap mold is filled with this swirling.
Since yellow makes me in a good mood, the soap glue was colored with annatto extract in different shades. The scent of course had to match the color and became a mixture of Litsea-Cubeba and Lemongrass.
If you would like to know more about this technique, feel free to watch my trailers for the online courses Advanced Part 1 and 2. There different techniques are presented to the course.
I think it is worth a look!
