I don’t usually sketch, I just start painting. I think I’ve always done this but sometimes I’ve found it necessary to do a couple of preliminary sketches in pencil just to solidify the layout. I’ve done some pen and ink drawings but the necessary sketching and subsequent tracing was tedious at best. I like being able to just load my brush and start painting. Although I’ve occasionally sketched onto the canvas I don’t find that it adds anything that I can’t do with a few quick brush strokes. I’ve often found that these quick strokes need to be corrected but it’s easier with paint than pencil so I just start painting.
