1/4 cup cornstarch
10 drops tea tree oil or lavender oil (use organic if at all possible)
2-5 TBSP coconut oil
Mix all ingredients together and place in old deodorant stick or glass container. Let sit to mold for 1 day.
Note: 3 TBSP coconut oil seems to be perfect amount. Look out for melting during hot summer months ~ keep in cool, dry place.
