I love gold leaf and have been experimenting with it for my book on alternative surfaces. Bleach is my new favorite art tool. On this piece the the surface was painted in a patchwork of color so I could see which I liked best showing through when I finished the next two steps. I added gold leaf (the cheap stuff not the REAL gold leaf) then applied the bleach pen. The longer you leave it on the more dramatic the effect. I then wash it off with soap and water. My favorite colors showing through are iron oxide and dark green.
