Sure, newsprint is probably the worst possible canvas for any kind of paint. It doesn't work well with watercolor and is known to deteriorate very quickly. So what?
After a quick warm up with my young friend, who does not care if we paint on canvas or newsprint, I did a quick sketch of the succulents in his backyard. It feels like handwriting to me, something that only I could have done.
It could be ironed and then photographed in better light, but hey, it's only on newsprint anyways!
