We were at a thrift shop not long ago and I picked up an old copper foil embossed piece done by a high school student in 1974. I only know that because his name and date were on the back side of the frame it was in. If you've never done foil embossing you'll find this little project to be fairly easy and inexpensive. You can substitute heavy duty aluminum foil for copper foil. This piece had a wash of India ink on top of it. This can also be replaced with watered down acrylic paint.
