Creative Grids Turbo 4-Pach Template Quilt Ruler- Create four-patch blocks in 16 different sizes ranging from ½ inch to 4 inch finished sizes. Place the markings on the ruler directly on the seam line and trim. Since the blocks are trimmed after cutting, sewing, and pressing, any distortion caused by these steps is corrected and each four-patch will be the perfect size every time! This trim tool is the perfect companion for the 2 ½" and 5" pre-cuts that are on the market. The template slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts! The template comes with fully illustrated step by step instructions or scan the QR Code printed on the template to view a video demonstration.
