The BERNINA Patchwork Foot #97D is designed for straight-stitching and is ideal for sewing ¼" or ⅛" seam allowances and top stitching. It is available for BERNINA machines that have a maximum stitch width of 9mm. The foot print of the sole fits perfectly with the feeding system for the most accurate feeding and stitching when piecing patchwork blocks on a 9mm BERNINA machine.
