I was at Whole Foods today and I found a bottle of Lime EO on sale. I figured that I could put that to good use in the den. When I got home, I dug out a bottle of P&G Old Spice Cologne that had been consigned to its resting place under the sink. With the help of my trusty tiny metal funnel, I hit it with a few drops of the lime EO, shook it for a while, and tried it out. Successful limification! Can't wait to test it out.
