Here is a picture of my first three batchlets from a week ago -- these are my "good try, but not good enough" soaps.
Left is an ITP swirl with a pale ultramarine blue. One drop swirl color is a deeper ultramarine blue and the yellow is from a bit of annatto infused oil. I like how the ITP swirl helps to bring the drop swirl pattern into the lower part of the bar. The FO I used (Bamboo and White Grapefruit from Natures Garden) smells nice in the soap, but it caused some of the bars to develop a rind of pale pink. Not sure why that happened, but, hey, whatever.
Middle is plain batter with a drop swirl of Hershey's special dark cocoa for one color and pink clay for the second. As you can see on the front bar, the swirl didn't go deep enough because I didn't pour from enough height. I think this one would be prettier if I had used a little less cocoa, a little more pink clay, and got the pattern a little deeper into the middle of the bar. I like how the generous amount of plain soap on the bottom sets off the deep colors of the swirl. The scent is Fresh Cut Roses by NG. This FO accelerates a bit, but doesn't discolor.
Right is plain batter with a drop swirl of ultramarine blue, ultramarine green, and gold mica. The mica turned an interesting coral-gold color -- maybe a little overkill on the amount of mica. I wanted the blue and green to remain light and "minty" colored. The swirl pattern is more wispy than the other two. I like that and I like how the base of the plain soap sets off the colors. I wanted the swirl to go deeper, however. The scent is an EO blend of lavender, rosemary, and Japanese mint.
If anyone has any critiques or tips to offer, I would be grateful for the help!
