  • Rolling Pin
  • Wax paper



  • Pinch off a small chunk of clay, roughly the size of a quarter, and roll it into a ball. Place it on a piece of wax paper, and use the rolling pin to lightly flatten it.
  • Use a stamp to impress a design into the clay. Use your fingers or a butter knife to clean up the edges and refine the shape.
  • Using the sharp end of a skewer, make a small hole at the top of your diffuser.
  • Create a few clay beads by rolling clay into balls roughly the size of a penny and using a skewer to create a small hole. I used white air dry clay for my beads, but my hands still had terracotta clay on them, giving them this pretty speckled pattern. Let everything dry overnight.
  • Cut a piece of twine about 12" long and fold it in half. Feed the folded end through the beads.
  • Then feed the folded end of twine through the hole in the stamped piece of clay.
  • Take the two loose ends of twine and feed them back through the loop of twine. Pull the beads through the loop, and then gently pull to get rid of any leftover slack in the twine.
  • Wrap the ends several times around the middle of a small clothespin and secure with glue. Trim off any leftover twine.
  • When it's dried completely, add several drops of essential oils and clip to the air vent in the car.


Add more essential oils when you notice the smell beginning to dissipate.
Rather than making your own beads, you can use colorful glass or wooden beads. Glass beads won’t absorb oils, so they won’t release a scent. But un-painted wood beads will, to an extent. To keep things simple and increase the fragrance released by my diffuser, I just made my beads out of clay.
