Today, just a quick snippet. Have you ever wondered how your sewing machine works when it has the two threads and only one needle? How is the stitch actually formed?
This cool video shows you exactly how that works. And now you know why the ‘timing' on your sewing machine is so important. If the timing is off, due to damage somewhere, then the stitches won't form correctly or you may get skipped stitches. Same if you have a slightly bent needle.
