Not sure about the results on Tuesday though it was an interesting exercise. We were doing wax resist though I used oil pastel with watercolour (plus some water soluble wax pastels).
First though some quick poses. About 2 minutes each. Left then right hand
Then just one minute. First left hand then not looking at the paper.
Now the resist. First 15 minutes on A2.
I added more wax for the longer pose. About 45 minutes on 30"x22"
