No info. on how thick to make or how to finish them as I haven't tried them yet, however as a woman, who wears earrings, I wanted to throw out that you do want them on the "light" weight side. Most women I know do not like "heavy" earrings. I have seen some patterns for wooden earrings and for me, they looked to big and bulky and like they would weigh a lot. Now that said, I also don't like big and bulky earrings but many women do - but even when they are big and bulky looking - they need to be as light weight as possible. Otherwise, they can start to hurt your ears after a while.
