The QuiltMaster Precision Ruler measures 12.5 x 18.5 inches, offering a versatile tool for various quilting and home decor projects. Its easy-to-read black and white markings include 1-inch grids with 1/8 and 1/4 inch increments, facilitating precise measurements. The ruler features black numbers on white dots and 1/4 inch grip sides for accurate cutting of whole inches, while the Turn-A-Round feature allows for 1/2 inch increments, guided by white numbers on black circles and a 1/4 inch grip side. Dashed lines on two adjoining sides assist in trimming seam allowances. Additionally, the ruler includes angles at 30, 45, 60, and 120 degrees, running in opposing directions, and white horizontal and vertical lines to help identify the center for fussy cutting stripes and borders. The design ensures smooth sliding over fabric, with an exclusive grip that holds fabric securely during cutting, reducing slipping and errors.
