No matter what you’re sewing, maintaining an accurate seam allowance is of utmost importance. Our Magnetic Seam Guide works to help you achieve a consistent seam width. It’s a small-but-mighty tool that clings tightly to your throat plate. Its rare earth magnet is rated at 3.5kg of pull. The magnet is recessed into a soft, rubbery material that keeps the guide from marring the surface of your machine. These Magnetic Seam Guides won't shift, with 3.5kg pull power. They have long, angled arms that aid in curved piecing. And there's a handy tab to facilitate removal from your machine bed.
