I'd just bought a brush pen and was experimenting with it in the first few sketches done a few years ago. The brush was a bit too thick and dominant for an A4 sketchbook and I wouldn't use it in a drawing that small now, but it was lovely to use. I've lost it now :(. They are mainly of Harlyn Bay/Trevose Head on the wild, rocky north coast of Cornwall.
The next few sketches were done a couple of years later and are of the south of Cornwall - a much gentler coast with drowned valleys creating complex tidal creeks overhung by woods.
