What are you most proud of? It worked! Surprise today, with the soap about 4 weeks old. I cut a bar and the interior did not darken. I'm interested to see if exposure to air or light is what caused it to darken. Anyway, it looks pretty cool! What advice would you give someone starting this project? Not advice, but the coconut lime soap has darkend significantly in a week. I need to learn how to make light colored soap that stays light colored. I'll make more soap this weekend.
