I lightly dusted the top of the cranberry fig with copper mica powder and the top of the almond biscotti with gold mica powder. The almond biscotti fragrance (from Bramble Berry) really turned the color of the soap a yellow, which I don't mind. I was expecting off-white and then for it to turn to light brown color because of the vanilla in the fragrance. I used vanilla stabilizer, and I do still expect the color to change over time. We'll see. I sprinkled cocoa powder between the layers for the thin line, and then topped with plain, unscented soap on top. I like how it looks now and I think I will like it as it morphs, too. I'll keep you posted.
