Place one C. of Epsom and 1/4 C. sea salt in a bowl or resealable plastic bag. Add 2-3 drops peppermint oil. Place the remaining ingredients in a second bowl. Mix all ingredients well. Layer the red and white salts in a clear bottle or jar. 1/2 liter water bottles work well because they have the stripes. Tie with a ribbon and some small candy canes. This makes a great holiday gift for friends.
