No, this has nothing to do with Hallowe'en :)
I started experimenting with acrylics and "adirondack alcohol inks." The inks kind of have a life of their own; they move and spread out in some interesting patterns. It became a bit of a mess so I decided to cover everything up with a couple coats of gesso. After the gesso was dry, I drew on the trees with charcoal, not easy to do on canvas. I ended up moving the charcoal with brush and water. The effect was great but I needed to protect the drawing so I poured a coat of self levelling gel over the entire canvas. Whatever the chemical reaction, the alcohol inks came through and I did not like how it made the trees look. So I painted bits of the trees with Golden Mars Black and Titanium White acrylic paint. What a mess. I then mixed up Golden Quinacridone Crimson and Cad. Yellow Medium with Golden Clear Tar Gel and poured this mixture over the trees. Another mess. Note that the painting had a high gloss finish. I next took sandpaper and sanded down the trees. Over the now rough trees I applied a bit more of Golden Mars Black and stopped. What you see is the end result!
