Mardi Gras Soap turned into Rainbow Soap (pix)
I had grand plans of making a layered bar with green/gold/purple. Since I only had LOTP liquid dyes, I poured a thin layer of clear in bewteen the color layers. Took this photo w/the light coming through the bar so you could see what it looked like. Guess it's more "rainbow" - I used a scent called "jewelled citrus".
