The Janome Binder Foot (9mm) is designed to apply pre-folded or self-made bias binding tape to the edge of fabric in one easy step. It features a small funnel that folds and guides the binding over the fabric edge before it reaches the needle. This foot can be used with straight stitches, zigzag, or decorative stitches, allowing you to customize your stitching and achieve a clean, professional finish. It’s an essential tool for creating neat, finished edges on a variety of sewing projects.
