Done with a simple tool merely called a Plastic Stylus...looks like a big needle in a plastic holder. I then used my Derwent Inktense Colored Pencils...love those cps. Only a 5x7 but this one is a favorite of mine and I cannot quit looking at it.
It is for sale, and I also have prints and cards available.
I have to go work on a framing job. Not even open yet and the jobs are starting to wander in. I'm so excited.
