My guy had a beading permit, but he just got it taken away. As far as marketing their products, they make contracts with people basically who sell their products. But I don't know anyone for horsehair and the people my guy sold his beading stuff to aren't doing it anymore. They actually can make a contract with you so you could sell it out here once you've bought it from them. Like I said, I don't know specific vendors. The prison may though! Lots of people do horsehair and beading so they have to know where the inmates sell their work.
