I made some soap yesterday with a new to me scent blend of Lemongrass and Myrtle essential oils, equal parts. Smells great that's for certain!
I used chromium green oxide and blue ultramarine powders for my colourants with a little green mica added to each and tried to do minimal swirling with my hanger LOL. And I did add Titanium Dioxide to the rest of the soap to whiten it up.
So its nothing too fancy, the fragrance is the star of these bars, and of course they won't be ready for Christmas. Here's a link where you will find the recipe.
