Every friday at the National Gallery in London is provided a few materials so you can observe the paintings and make a drawing. It is very funny, I’ve almost tried last time I was in England. You can click here and see the schedule of the days, rooms and hours available. It is awesome the way that the museum encourage the arts, at the museum shop you can also buy different types of painting materials.
“Join an artist and lecturer to explore a painting in two different ways. First, listen to a short talk, then make your own response by making a drawing with the materials provided.”
