I recently saw some cards on Pinterest, made with stamps and charcoal pencils. My mother, who was very creative, used to employ charcoal as a medium. She made up a picture of me wearing a ballet outfit (when I was 3) with a 2 x 2 photo as her guide. She also did some other canvases in charcoal, and also in oils, but I particularly loved to watch her working in charcoal.
I thought it would be fun to try this, just because it reminds me of my mom. It's nowhere near the calibre she did, but I enjoyed the process.
