1. Combine all ingredients in a large bowl; blend thoroughly using a fork. Using a tablespoon, fill several small muslin pouches with the bath blend. (Depending on the size of the pouches, this recipe makes enough for 3 to 4 baths.)

2. Tighten and secure the pouch strings with a tight knot. Or make your own bath pouch: Place several tablespoons of the bath blend in the center of an 8-inch square of muslin cloth. Gather the sides, and close the pouch using ribbon or twine. Store cloth bath pouches in a closed container (such as a Mason jar) until ready to use, up to 2 weeks.

3. To prepare a bath, place the pouch in the tub, and fill with lukewarm water. Allow the herbs to steep and the water to cool for [about] 15 minutes before entering the tub. As you soak, you can use the wet bath pouch as a soothing compress for sunburned skin. Soak for 10 to 20 minutes; rinse with cool water, and gently pat skin dry.
