Too cool! I just got a hemstitcher and I can't wait to try this.
For those of you wanting to do this on a conventional machine, the reason a specific stitch was not supplied is that it varies from brand to brand and machine to machine. The most common stitch used looks like a daisy with each pedal coming into a center hole. Almost any standard zigzag foot will work. The more advanced machines have many more options for the "hemstitch" stitch and may call it many other things including an entredeux stitch. My suggestion is to play and determine which stitch will work best on your machine. Use a larger needle to get a larger hole, even try a wing needle (a needle with flanges on two edges to make a larger hole in the fabric). Perhaps you need to increase your top tension. This stitch may require a finer thread to get a better look. There are so many variations. Check your owners’ manual, go on-line to your machine’s site and simply play.
For the lady with the Babylock Quest, as a starting point try #57 from Group 2 or try #37 or #57 from Group 4.

Good Luck,

I can’t believe my eyes. I have never studied in a school, but after years of teaching and sewing and reading everything I could get my hands on, I didn’t think that there was much more to learn. I must now repent my arrogant ways and go back to reading everything I can get my hands on. Bravo!! First I must applaud you for giving me a new trick (or two) and second for writing such clear instructions. I love this skirt and your beautiful stitching. I must also agree with you about cutting off the beads rather than smashing them. I do try to unchain them instead of cutting them so that I have the thread tail captured and can stop the chain from coming undone. Additionally, without the extra beads to cover the seam, your work is not as “finished”.
