The Creative License is my favourite book on drawing. In it Danny Gregory tells us to
'sign up for art classes, and even if the class sucks keep going to it until you've found another one to go to'.Tania got me a term's worth of watercolour classes at our local community centre (the Malden Centre) for christmas.
The classes dont' suck. The teacher simply comes up with a theme, sits down at the start of the class, talks through how he is going to draw/paint it, and then lets us get on with our own pictures. Its great fun, and playing around mixing colours is a whole new world for me.
