I’m a professional artist-this would take me hours and hours to get it just right, with a lot of glaze to get that transparency going. If you pick the Welder DNA Watercolor Version Shirt, don’t build up the layers correctly, don’t control the transparency, and don’t watch your negative and positive spaces, it’s going to be a big old gunked up mess on your wall. If you really want to do it, get a 50 percent off coupon from Michaels and get one of their huge canvases, and have a go on that. If you screw it up, you can just gesso over it and start again.
