Turn-A-Round™

See Figure 1. With the Creative Grids® logo facing you, cut your 1", 2", 3" etc. squares. Then Turn A Round™ your Creative Grids® ruler so that the logo is upside down and the numbers running along the bottom of the ruler are now right way up. You can then cut 1½", 2½", 3½" etc. squares easily because you are following the same black line each time.

See Figure 2. The same applies to the Turn A Round™ rectangular rulers: you can cut your 1", 2", 3" etc. strips then rotate your Creative Grids® ruler to cut your 1½", 2½", 3½" etc. strips.
