All Our Lessons Take Place Outside. The graffiti lessons are run by working artists and are done at the highest level of integrity and art. We teach technical graffiti skills along with general art education. The graffiti lessons are 1 hour long and takes place at either First St. Green Park (outdoors) located at 33 East First Street in Manhattan between First and Second Avenue or at AP Cafe 420 Troutman St. in Bushwick Brooklyn. The closest subway stop in Manhattan is the Second Ave. F Train stop and in Brooklyn the Jefferson L Train stop. Lessons are great for individuals, beginners, birthday parties, kids and adults. You can bring canvases, t-shirts, or other items to spray paint at our lessons for some extra fun. We also offer Master Classes with a graffiti art legend upon request.
