This left-handed version of the 12-1/2in square ruler from Creative Grids® is a mirror image of the original. Now those that cut left-handed can read the markings and numbers right side up. Perfect for trimming one of the most popular sized blocks used in many quilting patterns. A left hand icon is printed right on the ruler for easy identification. · Made in the USA with high quality acrylic and precision measurements ensuring accuracy for your quilting, sewing, patchwork, and crafting projects. · Creative Grids® exclusive non-slip grip allows you to easily slide the ruler over the fabric until positioned correctly. Then, when slight pressure is applied, the grip holds the ruler in place, eliminating slipping while you cut. · Easy to read black and white markings are printed in 1in grids marked in 1/8in and 1/4in increments. · Use the black numbers printed on white dots and the 1/4in grip sides to cut in whole inches. · Use our exclusive Turn-a-Round feature to easily cut in 1/2in increments by following the white numbers on black dots and 1/2in grip sides. · The 1/4in dashed lines that are printed on two adjoining sides aid in trimming seam allowances, and the 45 degree diagonal line makes trimming half-square triangle blocks easy and accurate. · White horizontal and vertical lines are printed on the square to show the center of the ruler. Use these lines to square up blocks based on four-patches, embroidered, and appliquéd blocks. · Scan the QR Code to view a tutorial video on these features and to see the patterns that can be made with this ruler.
