Sorry I didn't think of that! A Dritz seam guide (metal plate with measurements for both straight and curved surfaces) is a big help, or make your own out of pasteboard. Actually, the pasteboard version might be better as the metal can overheat.
Better to press (up and down motion only, no sideways) than iron. Ironing (moving the iron sideways) can distort the fabric.
