I really wish the low shank buttonholers for zigzag machines were more common, they are great for zigzag machines that takes top stitch thread well. I have used up to date modern one touch built in buttonholers, they can be the best, but still, not all are. I have come across late 70s buttonholers, working in the same way as the old, moving the fabric left to right, not just along the seam line of the buttonhole. I guess there were various kinds made. I have too many machines to add a slant shank at this point :- |
