There are some things in life you don’t want to be lazy about. Lots actually. Things such as: what side of the road you drive on… or… getting to the airport before the plane leaves. Things like that. Then there are the other less obvious things. Such as: change the water in your container before it’s a swamp. Long before. Because when you use that dirty water to paint with, it is subtly dulling down your colours. It really helps to have a larger container for water. 2 litres is good and the water won’t get dirty nearly as quickly as with a little container. Don’t be lazy – your art deserves better than that.
