I typically paint murals directly on the wall, and have painted murals on canvas before, but they were tacked up. For an upcoming ceiling project, I will be working on muslin. I was told by another artist to only prime the front, is this true, and also if my space is roughly 16x18, do I paint the whole thing this size (plus extra for shrinkage- and how much rough shrinkage should I expect) and have it installed this way, or does it need to be cut for installation?
thanks so much
