I have done it. I used 50/50 bayberry - beeswax. I used bayberry wax from blocks purchased online and the smell was nice and subtle with the beeswax. I love the smell and would have been happy with it stronger. I've never tried to render the wax from bayberries and I don't know if gentle temperatures would render a stronger smelling wax.
I do wish you good luck. If I could get my hands on bayberries or grow them myself, I'd be trying it, too. Keep us posted.
