This amazing ruler brings the "tacky technology" to the quilting world. The Ideal Quilt Guide is 15 inches of straight, 1/4" crystal clear acrylic that will help you accomplish straight-line quilting for both sit down and long arm sewing machines! Use the tacky rubber side to adhere to the fabric and simply run the sewing machine foot along the edge to achieve perfectly straight lines. Flip it over and use the tacky side to gain ultimate fingertip control of your guide to bury those 'not-so-straight' stitches in the ditches. Cleans easily like the Ideal Seam Guides using a multi-surface cleaner like Fantastic or 409 to loosen the lint. Then you should rinse with warm water and let air dry or use a hair dryer if you just can't wait to get back to work!
