I'm a quilter, and I would like to find a way to use my iPad to support my creativity. Art Studio looks interesting, but I don't know if it will work for what I want it to do. Basically, I want to take a picture of my quilt and then be able to draw various quilting designs on the photo to try out the designs before I actually stitch with thread. Any thoughts about how Art Studio might support that? Are there other art applications that might work better?
