Our teacher (one of 5, and also apparently the founder of the company) was a positive, likeable fellow who fell in love with graffiti in Argentina then returned home to NYC to start the NY graffiti tour business, then latterly start teaching lessons. After a whirlwind 5 min history of graffiti (the whole lesson is only 60mins), he discussed paints to use, nozzles, and styles, then went on to demo technique. Almost immediately we were donning gloves (and the few extra shirts two people got to use as coverups) picking out our favourite colours and practicing our "tag" on sheets of canvas he had stapled to the walls of the small indoor Brooklyn Graff studio. He covered the various stages of design and walked us through execution. He helped keep everyone on track and moving towards the goal by doing some outlining (of a word of our choosing) which we then practiced filling in and blending (definitely a skill that needs more than 60 minutes to perfect). His assistant was a (too??) enthusiastic character of a veteran graffiti artist who was perhaps a little too involved (though thankfully with another group). Though we were quite pleased with our canvas for a first effort, we ended up not taking it home as we are travelling a lot in the week to come, but we were given various options for it being sent to us, or packaged in a $10 travel tube roll for us to take with, which was nice. In all, a very positive experience. As an added bonus, the area around Graff Studio in Brooklyn has a lot of street art, so we did a mini walk around the (industrial) neighbourhood in the 30 minutes before the class and saw some inspirational pieces.
