Hi everyone, it's Kat! Yesterday I had the pleasure of teaching a one-hour private class on in-the-pot swirling and made this fun 3 pound loaf. The colors are yellow mica, cellini red mica, activated charcoal and ultramarine violet. We wanted to stick with all-natural scents and came up with an exotic essential oil blend of Ylang Ylang, Grapefruit and Orange Valencia. The results are fantastic! I could see these colors working beautifully with a Patchouli (or patchouli blend) soap. Love it!
