I pretty much follow the Prism method, too. I start with the batting on bottom because it's easier for me to smooth the backing on to it. The batting seems to lay still better than the backing fabric does. As Prism said, it is important to spary half of so at a time and smooth things out. I didn't do that the first time and had so much batting fibers stuck to me I looked like an albino gorilla when I finished.
