Watercolour Class, and a challenge

I teach a class for the local art club. On Wednesday evening I set a challenge for the students to sketch something every day until we resume in January. Could be pencil, pen or paint as long as it's a sketch of some sort. One of my favourite artists, Ken Howard RA, said drawing every day teaches you so much about observation and will transfer to your paintings.

The plan is to review what we have drawn when we resume. Whether or not they all do it I don't know but I must set an example. Not as easy as you think, trying to find something to sketch. I picked things up, put them down, didn't fancy that, or that, etc etc. Eventually I settled on a pepper mill and got to work. Today's was easier, I just looked out of the window and got drawing. Neither took very long. After all, the point isn't to make a work of art but just practice drawing.
So here are my first two sketches in a little A6 size sketchbook. I'll post more as I go along.

What do you think about daily sketching? Let me know.
