I have done a lot of scratchboard in my time, and that is one reason I got into intaligo printmaking so much. It is similar in that I scratch the image in the rosen before submitting it to the acid.
I am a multimedium artist, and work in oils, acrylics, watercolor, printing, fibers, pastels, and sometimes all on the same piece.....lol
I have been desperate to find other printmakers and fiber artist though. They seem to be the most scarce online and off. If you have any suggestions I would love to hear them. It gets lonely out here....lol
