Going back to my post of the 22nd, in which I was using my new colourful sheep design and completely ruined a joke which relied on a fairisle jumper being very obvious.
I've tried my new sheep design in black and white, using a little hatching. It's something I want to be better at. I keep revisiting this particular file and having another go at the shading. Here's the current version, it's not looking too bad, and I think it solves the aforementioned problem.
