I also caught a show at the end the other day--they were tearing brown paper bag-like paper, crumpling, then painting with a 3 part equal mixture of qlaze, paint, and I didn't get the third ingredient. the paint was then wiped off to show the crumpled ridges. Then they glued? the pieces to the wall. I'm wondering if the 3rd ingredient could be wallpaper paste. Do you know what the mixture was ?
