Thanks for the encouraging remarks guys, and I really appreciate the specific praise Corky!
Squared Edges: when I created the template I use for creating labels, I put down a a square that covered the entire canvas, then cut out a circle that was slightly bigger than the canvas. I did this simply so that I would not be blind to what was happening right at the printable edge. Acually, for my own purposes, I do not save the final graphic with the template in place. I did it for my posts because some of the unprintable areas were "unsightly", and I did not want that to counted against me. Plus, it gave me a spot to add a signature (self-promoting, I know...)
