I attempted to swirl through the entire batter. I filled four squirt bottles (I purchased these in the home goods section of Wal-Mart), and filled each with a different color. One was activated charcoal, one ultramarine blue oxide, one titanium dioxide, and the final was yellow oxide. I squirted layers of color, zig zagging one at a time left to right, until it was filled. This recipe moved very slowly, and I had plenty of time to work.
I also premade a handy swirl tool out of chopsticks, also purchased from Wal-Mart, stabbed through a cardboard flap I cut off a box I had. I then lined them up and taped them secure. After the fact, I noticed the lines upon dragging seemed too close thus not highlighting the lines as well as I would've liked. I think a 1/2" space is probably much better than the 1/4" I had made.
After the first drag, I inserted a skewer and made the s and backward s pattern so familiar in the peacock swirl.
After all is said and done, there's some things I've come to learn through this experience.
A final note... Now that the soap has cured almost 8 weeks, I've noticed that the fragrance has morphed some. It has a slight undertone of the doughy smells now. I did attempt a full gel on this soap, and now I'm wondering if the heat might have had something to do with it. Others can smell it, but not as strongly as I can. All of our sniffers are different, so I'm going to have another go at it. I'm going to soap sweetgrass again and this time use buttermilk and freeze the soap. Hopefully this will prevent any morphing from happening to the scent. It is a lovely scent that I am in love with out of bottle. If I am not pleased with it, it may be purely a personal thing. The fresh and green scent is so wonderful, I may use it instead for lotion and wax tart melts. Never discard a scent that didn't work out with cp soaping IF it is something you love out of bottle. There's a million diy projects out there affordable and easy that can put good use to those fragrances that misbehave in cp soaping.
