Another class I taught was called "Many Windows." The students prepared canvas backgrounds with paint and/or collage. They then made collages on 3" square wood panels. (I'm very grateful to my stepdad, Rob, for cutting 150 pieces of wood for me!) When the collages were finished, the students glued them onto the decorated canvas, creating a mini art gallery.
Here are some pictures of work in progress and finished pieces. Each piece was so different and so lovely. I'll let the pictures be enough description.
