Finally got around to playing a bit....found out that the ONLY tucker attachment I have for my "more modern" machines is missing a screw!! :( So I had to resort to the 9W's tucker to show you what it does...unfortunately, I can't get a photo of the "line" that it makes on the fabric, but you'll get the idea.
As you sew the first line of stitches, the tucker makes a mark that is a guide for folding the fabric for the next line of stitching.
Please ignore the "patina" (dust) on the machine!! :lol:
