Re: "Essential
oils" (i.e.
lavender oil) question from a US user -- Look for an herbal shop, health foods shop, or a metaphysical shop. You might also have a go at a natural cosmetics shop (usually something only in large cities-- I saw one last, in Toronto). Otherwise, you might try as a next to the last resort, the candle/soap making aisle at a place like Hobby Lobby or Michaels/MJ Designs. All else fails: Google it. :D Good luck!
