I've just signed up for Tammy's Digital Dreams Workshop on willowing.ning.com.
I've done several mixed media painting courses with Tammy, she is an excellent teacher. She provides you with videos to keep. Using videos works for me, you can pause them and rewind them. I have found that I am much more pleased with my paintings since I started taking Tammy's workshops.
This workshop is about using photoshop to create portraits. It is designed for "full blown" PS, but should be adaptable to elements, which is what I will be using.
