Very pretty soap, Grere, but cinnamon is very sensitizing so I'm anxious to see how this amount of the powder works in soap once you lather up to use it.
SHORT STORY: I was in a swap once where one of the participants made "Extreme Cream" scented with cinnamon. I opened it as soon as it arrived and applied it to the crease above my eyelid because it was itchy. YEOW! Instant pain. I ran to the sink to deluge it with cold water. No sooner had I done that, when the phone rang. A fellow soaper called to report the same thing happened to her, only she had rosacea and spread the cream on her face!
She was in tears. Both of us suffered burns that took some time to heal.
Just a head's up -- cinnamon should always be used with a light touch. Whether that also applies to the powder, we shall soon find out.
