Singer Simanco 121704
This attachment for low shank domestic sewing machines produces neat buttonholes from 3/8" to 1" long. The spacing of stitches, width of stitch and amount of cutting space can all be changed at will. By using a slightly different technique it is also possible to make buttonholes up to 1-7/8" long. The attachment is operated by a lever which engages with the needle clamp.
