I did it! I put it all together and it's in my armpits.
http://littlehouseinthesuburbs.com/2009/03/quick-stick-deodorant.html I used that recipe, used more cornstarch than baking soda since my armpits are sensitive, and used just lavender oil instead of tea tree. I like the smell.
I'm sweaty. A day just like this where I used the Tom's of Maine roll on crap left me smelling almost inhuman. I smell just fine right now. It's working! It's cheap! It's coconut oil!!
