A couple of years ago, I took an online class on fabric painting with Sue Beevers at Quiltcampas. I just checked the website and they are no longer giving classes. If you ever get a chance to take a class from Sue Beevers, please do. She is very patient with people and you do learn a lot. When I took my course, I could only actually do two lessons with the group, for the temperatures weren't warm enough for me to do the painting outside. We did a lot of splatters and stuff like that which were messy. I eventually used two card tables, put one on top of the other, tops facing, wrapped plastic around the legs on three sides, put a piece of plastic over the top, and made myself a paint booth. I leveled out the working surface with cardboard. It worked very well and could be torn apart when not in use.
