My favorite base for my mixed media work is cardboard. I have a
friend who keeps an eye out for pieces she thinks I might find interesting. This
morning she wrote and sent me a photo shown below. Asked me if I
wanted it; YES, I want it. It looks so fascinating as a jump-off
point for a new project. I’m thinking weaving but could be
something else. Here’s where I need advice: does anyone know of a
good safe coating I can use on the cardboard to preserve it and yet
keep it flexible? I can see covering these pieces on both sides with
an acrylic medium, but I’m not sure because I want the pieces to
stay flexible. Ideas? Thoughts? Recommendations?
