I used to draw life models in College many years ago. Very worth while to the artists, but quite demanding on the model, as they have to stay in the same position for such a long time. Can't tell you much on pay, but if you do go ahead with it..try not to fall asleep...one of our models did and clearly had an erotic dream....as most young men do....but it was a real pain having to keep adjusting our drawings.......Oh and probably totally embarrasing to him when he found out....;)
