it never occured to me to make one's own deodorant. I've eschewed conventional deodorant a couple of years ago, but am still in search of an effective one.

I seem to be able to use one product (like the rock) and be effective for a couple of weeks and then suddenly I stink. Then I switch to another natural roll on which works again for a couple of weeks then I stink (mind you, nobody but myself seem to be able to smell this, and I have one stinky pit and one non-stinky pit )

I find that my merino wool shirts actually hold a bit of stink but somehow they disappear overnight. Amazing stuff.
