See? There ya go!!That is a good point! You may have given me a selling point on why I need a treddle. Just think of all the exercise I will get!
Need another reason? How about one I learned at an antique sewing machine symposium many years ago. The only truly straight stitches are sewn on antique machines - Singers and others - those WITHOUT zig-zag capabilities. Surprised? So was I! Turns out that under high magnification it is clear that the old machines sew with each stitch straight in perfect alignment with the one before. But with zig zag capable machines, even top line models, there is a slight slant between each stitch. It goes to the left at the end of the stitch, then back to right at the beginning of the next one, over and over again. It’s not enough to affect the finished piece, and it is only obvious under that high magnification, but it’s there, nonetheless. If I hadn’t seen it with my own eyes, I wouldn’t have believed it.
