Faux tooled leather.
After making a mold (far right) of the wallpaper (center), I used the scrap clay on the left to press into the mold, ran a tracing wheel around it, poked the hanging holes in it, then I baked it. After it cooled, I antiqued it with acrylic paints and baked again. I added feathers, jump rings and a leather cord. It was fun.
