Working on my stone carving.

Here is my stone carving/engraving I've been working on.

I've washed off the stone piece several times w/ soap and water but the original purple sharpie lines I drew the design with remain. I love the hyper realistic details of this picture.Not only can you see the purple sharpie lines clearly, but also every mark with the chisel ... even the little lines that are outside the drawing. you can also see dust around the eye from carving.

Every few minutes I must blow the dust onto the floor and then at the end of the day i will wipe the dust up with a wet towel.
