What Quilty's Mary Fons, has to say:
"This ruler is as essential to me as my rotary cutter -- no kidding. It allows you to cut half-square triangles and quarter-square triangles from strips and that is a great way to get them cut accurately. Many of the F&P patterns give instructions using this ruler, so that's handy, too."
