I've been taking an online class with collage artist Jane Davies, and it's been very enlightening. I've been introduced to new ways of using text and images, and most interestingly, paint. Now, I've spent most of my life painting, but for some reason it never occured to me to use paint on my collages. It certainly adds a new layer to them.
She also has a blog where all the participants (from all over the world) download their projects and we can comment on each others, etc. It makes for a very interesting method of learning, as besides what Jane demonstrates in her weekly vids, we can see how everyone else is interpreting the assignment.
Very much fun!
