The Janome Quilt Binder Set is the perfect accessory for quick and trouble free binding, with a superior design based on industrial binding attachments. The cone on the front of the fabric holder feeds and folds fabric for a 1/2" finished binding. Two upper screws on the binding allow you to adjust the fold of the fabric - set them at the same length for a straight stitch, or set the bottom a bit further that the top for a blanket stitch
