Desert Daydream blends sweet orange and cinnamon leaf essential oils and results in an almost-edible scent. Use about a 3:2 ratio. I also add dried flower petals, no colorant, so it is a creamy soap with flecks of color from the petals.
My lavender-oatmeal soap is still one of the most popular. I use a blend of cinnamon leaf, cedarwood, and nutmeg essential oils for a woodsy, more masculine scent and color it with green French clay.
