Freehand Quilting Foot 29C for Bernina sewing machine models 450, 640 and 730 with a 9mm swing is the preferred foot for freehand quilting, freehand monograms and freehand embroidery. This foot has a CLEAR sole, for improved visibility. The 9mm wide needle opening and the "coded" eye allows the use of any stitch at any width and contributes to good visibility Combined with Bernina's Hopper Mechanism, this foot gives excellent fabric control (no flagging) while the stitches are being formed as well as the ability to move the project freely under the foot
