Well, here it is. It’s a beastly-looking thing, isn’t it? I’m not sure how much I’ll use it but I’m anxious to try it out and see how it works. Thank goodness the instruction booklet is a bit better than the typical translated-from-Japanese manuals that often leave me scratching my head.
Since some of you asked, this is intended for use on an industrial straight-stitch machine but will also work on a commercial zigzag (like my Singer 20U-33) set for straight stitch. This is basically just the industrial version of the old Singer/Greist buttonholers made for straight-stitch machines – the ones that came in the old dark green (for vertical needle) or maroon (for slant needle) plastic boxes. The attachment moves the fabric back and forth but width and length has to be set manually since there are no templates.
