A few weeks ago I did three paintings in Bishop's Garden. The paintings are smaller than my usual work, which is because I made them inside a wet weather dry box I invented. It's an upside-down tupperware storage box with two holes for your hands, so that you can paint without having to worry about the English weather! The box is fully waterproof and of course very light and portable.
The paintings didn't win any awards but I did get a prize for my invention.
