No need to pre-iron your bias strip; the Tape Binder Foot automatically folds a 1.5" bias strip at the same time it is applied to the fabric edge. It is the perfect finish for blankets, placemats and jackets. The binding is secured with the Chainstich. The Tape Binder clips onto the front of your 1100D/1200D and guides and folds 40mm bias tape perfectly, doing away with the need to pre-iron. Ideal for sewing straight fabrics to curved, finishing difficult T-shirt necklines, etc. with ease. Use the Tape Binder Foot with the Attachment Holder (Part No. 200813103). Must use Tape Binder #200813000 and Attachment Holder #200813103 together.
