I have one for my Janome 3600 and it was invaluable making flannel nursing pads for my daughter. I used 3 layers of white flannelette, cut a square bigger than the size I wanted to make and used an embroidery scallop stitch in a circle the size I wanted. Then I trimmed around the scalloped edge with small scissors. My daughter loved them, they were easy to toss into the wash, they were absorbent, and it saved using disposables.
