This ruler designed by Karla Alexander for Creative Grids® cuts quarter ovals, half, and full oval shapes in a variety of sizes ranging from 3in x 4-1/2in to 8-1/2in x 10in and every half inch in between. · 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. · Use a 45mm or small rotary cutter. Hold rotary cutter straight up and down for ease of cutting and guide it along the inside edge of the curve. · Designed to be used in a variety of ways, so additional markings are included for techniques such as fusible applique, piecing, and turned-edge appliqué. · Easy to read black and white markings. Placement lines labeled A, B, and C give you three different size options with each of the twelve cutting slots. That’s thirty-six different sizes with one tool. · 45 and 60 degree markings give the option of cutting from pre-pieced patchwork like half-square triangle blocks. · Half-inch grid lines help you line up on the fabric, especially when cutting frames. · Guide numbers are printed on the ruler detailing width and height of ovals for quick reference. · Comes with fully illustrated step by step instructions.
