Echoes of Frank Stella

Here's a small (6" x 12") paper wall sculpture using the same image as my previous mobile, this time with the paper folded into a grid of pyramids and squares. I glued the paper onto a piece of birch plywood and then scalloped the edges to follow the outline of the paper. This piece is meant to be practice for another one twice as large. I'm not sure if I should stain the exposed wood border or not.
