As it happens I wasn't late and had plenty of time to set up.
There was a very good turn out, didn't have a chance to count heads but there must have been 30/40 there.
I worked in acrylics and to be honest I think I spent too long on it, I went back into the sky and fiddled with the foreground - I must learn to paint slower.
Hunstanton Demo 14" x 18"
Cows at Dedham 10" x 12"
This 12" x 10" picture took even less time so I had finished well before 9pm so I fielded a few questions and gave a few more hints and tips about painting plein air
At least I know how to get there now.
