During art school, I HATED chalk. I could work with pastels/ chalk just fine, and I really had no choice, but I hated the mess, the feeling in my hand (this was an issue with chalk from the time I was little writing on blackboards). Man I wish I had the patience for those large scale drawings though! My medium of choice is Acrylic paint. I am too impatient for others like oil, and I tend to overwork watercolors...
