I have been conducting various experments with foil etching. I am
trying to do foil etched picture frames inspired by Mexican tin
frames. I have conducted a variety of experiments and many of the
results have been dissapointing. The best one was one I did with
foamcore, a fat primary pencil and black acrylic paint. I wiped off
the wet paint with a damp paper towel. I got one good product but
sometimes it still doesn't come out. Can you give me some pointers?
