I just got my membership packet in the mail today from the Portrait Society of America. I'm very proud to be a member and to connect with this great organization. I first became aware of the Portrait Society in 2013 when I won a scholarship from PAFA to attend a Portrait Society conference in Philadelphia. I met a ton of great people at that 2013 conference including George O'Hanlon from Natural Pigments. I knew I wanted to become a member at some point.
The membership packet that they sent me is really nice and you can tell they care about their members and materials. If you're interested in portrait painting I recommend you check them out :)
