Marsha's Comments: Do you ever have the problem of finding the right lines on your ruler when cutting down your half-square triangles? This handy ruler eliminates all that because the ONLY lines to see are the ones you need! Two sides are used for half-square triangles ending in half inches. The other two sides are used for those ending in whole inches.
