What it does: A polygonal seam guide made from strength ABS that mounts to your sewing machine with a strong magnet to lock position and keep seams stable. Clear measurement markings provide precise stitching alignment for consistent hems and seam allowances. Why you need it: Reduces guesswork, fabric waste, and rework by keeping needle alignment steady and visible. The magnetic hold prevents the guide from shifting during sewing, so seams stay accurate from start to finish. Key attributes: Material: Durable, damageresistant ABS for longterm use and reliable performance. Function: Acts as a seam guide and ruler to improve hemming, edge stitching, and alignment. Markings: Clear, easytoread measurement lines on a polygonal guide to set and maintain consistent stitch placement. Attachment: Strong magnetic connection secures the guide to compatible sewing machines for stable operation. Performance benefits: Produces more accurate, repeatable seams and hems. Extends the life of the tool by resisting wear and impact. Simplifies tasks for both hobbyists and students during craft or training sessions. Practical uses (examples): 1. Hemming trousers and skirts — set the seam guide to the desired allowance and run the fabric along the guide for even hems. 2. Quilting and straightline stitching — maintain consistent seam allowances across long runs of fabric to improve finishedpiece quality. 3. Garment and craft projects — align patches, edge finishes, or decorative topstitching with clear measurement reference. Compatibility note: Designed to attach with a magnetic hold to sewing machines where a magnetic seam guide can be used. Confirm magnetic mounting is suitable for your machine model if uncertain. Summary: A sturdy, magnetic polygonal seam guide with clear measurement markings that improves sewing accuracy, prevents accidental movement, and delivers longlasting performance for a wide range of sewing and craft applications.
