My Collagraph Kit! It contains a variety of collage materials including corrugated cardboard, embroidery floss, tacky glue, metal tooling foil, seed beads hole punch, sheets of thin cork, and thin chip board.
Here are my experimental collagraph plates. I collected materials that were readily available in my art room that students could realistically use to make their own collagraphs. You can see that I used buttons, foam scraps, various ribbons, wood stirring sticks, embroidery floss, and even some scraps of metal tooling foil!
