Start this project by creating a few pages of rubbings. My favorite was the lego!
Then create a template and cut out 1 inch squares from the rubbings. Place a plastic page protector over the template. Using the template as your guide, add the squares between the two sheets of plastic.
Use a sewing machine to stitch around the squares. Remove the template backing.
Create a textured board to mount your rubbings on. I used hard molding paste and layers of black glaze.
Tack, nail or screw your plastic pockets of rubbings on to the textured background.
