Paint sticks come free when you purchase a gallon or a 5-gallon bucket of paint at any home improvement store. If you can’t grab some for free you can always purchase 1/2″ x 2 strips of pine in the lumbar section, as well, which is comparable to the 5-gallon stir sticks you get at the paint counter. If you want them in large quantity you can purchase them for about $.45 each from here. I have done quite a few fun projects with these little strips of wood.
