The first time I heard about this swirl is from Otion Soap Blog, see their original post: Elemental Swirl
This is basically doing ITP (in the pot) swirl 2 times with 2 different color schemes, separately. Usually it is done with one ITP, pencil line on top, then pour the 2nd ITP on pencil line without breaking it.
My problem is, to do ITP my soap batter has to be relatively thin to medium or else colors don't swirl within. But to ITP first then pencil line before the 2nd ITP will make my later one too thick to pour. Why? I'm slow and annal... it would take me time to do my perfect pencil line and clean up all sides before the 2nd ITP pour. My typical restless mind started to roll, is there a reason why I can't pour both ITP at the same time?! What's stopping me?! Is pencil line really important in this case that I cannot live without?! What's the purpose of the pencil line? To separate the 2 ITP, to prevent the 2nd ITP to break and mix with the 1st ITP. But, if I pour my both ITP at the same time simultaneously side by side, they should be able to hold each other's territory without help from pencil line.
Here it is, Sandalwood Rose
(This is by no mean the typical sandalwood rose, it's my own blend. This is sandalwood without sharp camphor note, sweeter with a powdery finish, plus a none typical rose, I used Alaskan wild Denali rose instead.) If you are interested you can get a bar here: Buy Sandalwood Rose Soap
And no, I did not use a divider!
