I saw the tools...they ere perfect squares I'm quite sure ...Am I wrong? I didn't measure them.... But they cut out perfect squares...! ? Your directions speak of two different lengths?
I did see the tool on a site that showed it's lines are 3/4" in from each corner except one corner is 1 1/2 inch in from edge .... Then, also remember to be sure to always use the tool the same way and not twist it's layout. . .Note: which location the 1/12" corner was held on the intersecting seams when you are drawing around, or cutting around each piece . . .must match up the pinwheel colors just right... . . . So hold / place it down the same way.... Any more help? I want to cut and make the tools today...
