For this I just used a lighter color and I drizzled it in straight lines on top then I folded it in. From one side and the opposite side. Then I repeated the drizzle and fold and dumped it in the mold.
Looks sooo nice. You swirled that before you had it in the mold? Maybe I should try that!!!! My first swirl was dedicated to my 17 yr. old son. Cocoa swirls!! Looked more like white cake with chocolate frosting!!!!! After I unmolded it, he came from the kitchen with my squiggle lined potatoe masher and told me to try that next time, then ran quickly from harms way Wise guy!!
After awhile of looking at the soap I thought maybe he has an idea!! just don't tell him I said that!
