What type of piece is this? Collage/Mixed Media Share a little about the materials, processes and techniques used to create this piece. Pack of foam sheets at the craft store...what can I do with these? Cut them into pieces and glued them to a canvas. Several coats of gesso and grey acrylic paint left to dry. It looks like broken egg shells. Thought...you have to break an egg to make an omelet. So l painted the egg. I think it looks a little like some of the photos that came back from the Hubble telescope. Is the piece for sale? No What are you most proud of? I loved painting the bubbles.
