1. In a bowl, combine baking soda, cornstarch, essential oil(s), and vitamin E; mix very well with a spoon.

2. Mix in just enough coconut oil to hold it all together.  It should be a solid paste, NOT liquidy.

3. Smush the mixture into a few jars. Let it sit for a day or two so that it gets sturdier.

4. To use it, wet your fingertips, get a bit of the paste on your fingertips, and use your fingers to rub it evenly on your armpits.  Use very little. (Don't use so much that you get a white residue on your armpits.)
