One of the exercises we do in the first week of my watercolour workshop are paintings of pears. They are nice bulky and speckled shaped fruit to study and to paint. We paint pears in the morning and after lunch, and a bit of wine, paint a full throttle nature morte.
A friend wants a couple of them so I scratched through my work files and I have posted some that I painted as demonstrations below. I should add that they are not really finished but just demonstrations to launch students into the exercise. But underdone watercolours are by far preferable to anything overworked and muddy.
