Column swirling is done by pouring many different color soap layer by layer onto a square column object at the center of the mold. Then after filling up the mold, you take a skewer stick and draw fan pattern lines inward or outward. This was my first take, unfortunately the fragrance oil I was using caused acceleration, made the pouring not as free flowing as I expected.
Very colorful, some people think it is rather, psychedelic! And if you are interested it is listed in my Etsy shop: Secrete Lover
