I signed up a while ago for the dover design sampler at
www.doverpublications.com It's emailed automatically weekly. This
week there is a "coloring page" of a painting by Morisot. I used
one of these (Picasso's "Three Musicians")a few weeks ago in class.
I gave it to three students who finished their projects before the
rest of the class. They colored them in, and for the next class I
showed them Picasso's version for comparison. One of the students had
rendered the picture in different shades of red--it looked really
interesting--and we talked about Picasso's blue period. It worked out
very well; it's a good little project to have as an extra.
