what are the challenges to airbrushing on canvas? base coat with gesso or a layer of acrylic first? i sold an old gpu and can get a 7 meter x 1.5m roll with the profits. the paper i have now is okay to practice on, but once you up the liquid content and blast on heavy paints, the paper really shows its limitations. ive seen some higher gsm paper online, best deal i can find in oz is about 24 sheets of 220 gsm A3 for 10 bucks... i may order one and get more reject store sketch paper to practice with.. basically 7 dollars for 120 sheets?? of 120 gsm.. but im ready to step up and try to make a piece or two im going to try and gift or sell.. 7 dollars for a 2 meter x .4 meter canvas.. or i can get the 7m x 1.5m for 50 bucks.. well 70 if i have them deliver.. any thoughts on airbrush to canvas? i will be combine airbrush, and hand brushes..
