The 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 inch 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 than the top for a blanket stitch.
