Hey, dude. That's a great idea, and I'll definitely be giving it a try. I had an idea while watching, though: why not save some time by cutting out the patterns into a plastic sheet (like that on the front cover of a heavy duty spiral notebook), laying the plastic over the taped card, spray painting through the cutouts, and then just cutting around the paint. That way, you don't have to trace the patterns onto the back of the cards every time you want new targets. Just tape, paint, and cut. Thanks for the video! -New Subscriber
