As I recall from that book, she uses templates, prefers cutting the template with the seam allowance included, thinks people can quickly learn to eye the quarter inch seam and advocated marking the points for precision matching, but I don't remember with what marking tool. You can probably get a used copy of that book very inexpensively on Amazon or eBay. She also has a website, so you could probably pick up which techniques she favors by getting acquainted there.
