I enjoy drawing so much. It is a form of expression and release for me. What about you?
What instrument do you use; graphite pencils, pen and ink, inked brushes, wax colored pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers?
I use them all, but my favorite are the paints and brushes. I feel like I can express myself with the colors, especially with my abstract pieces.
What type of support material do you use, cardboard, plastic, leather, canvas?
I like to use the canvas. Do you like drawing?
I do not really like drawing. It is good that you used canvas,  The medium has been a popular and fundamental means of public expression throughout history.
A pity you are totally missing out. I like the way the canvas makes the painting look. I had no idea about the history behind it.
Before you use paint on your canvas, do you initially engage in a quick, freehand drawing, usually not intended as a finished work which is called a sketch?
Before I paint I must first turn on my classical music and yes then I do a quick free handed drawing. You seem to know a lot about drawing for someone who does not like it. Maybe you should try it.
I know a great deal about it especially its use in commercial illustration, animation, architecture, engineering and technical drawing.
