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 markings printed in 1in grids marked in 1/8in and 1/4in increments. Dashed lines are printed 1/4in away from both 6in edges to aid in trimming seam allowances. The 1/2in line is clearly defined through the center of the ruler. Total Size – 1in x 12in This small 1in x 12in rectangle ruler from Creative Grids is a great tool to keep close to your sewing machine for quick measurements and for marking 1/4in seam allowances when needed.
