When you realize you’re never going to use that set of watercolours (you were going to be the next Monet!), donate them to the Toronto District School Board, and let a student experiment in your stead. A wide range of items are accepted, from hanging file folders to sewing machines and fabric scraps. See a partial list of accepted items here.
Artsjunktion accepts donations on Tuesdays and Thursdays from 10:30-1:30, and 2:30-5:30.
