Long ago, in the ancient days of Compuserve, there were many forums. On one forum, I saw a conversation that interested me. A woman was being married on the spring equinox and wondered if there was a specific oil that would be appropriate for that day. Someone answered her and said that a patchouli and rose blend would be the one she should wear.
I never really checked it out, but it seemed like a really lovely idea, so I mixed up the combination. We had been having trouble with the rose fragrance that we had been using fading too quickly in soap - and patchouli is known as a fixative oil, one with properties that make it, and anything it is mixed with "stick."
We made the soap and the fragrance of the rose was most prevalent with a tiny bit of "something" mysterious added.
It is a beautiful shocking pink and have been selling it every since. Always popular, but especially now on the Spring Equinox - our Patchouli/Rose.
