Felisa Nakazawa posted the video above on Facebook today, giving a completely machine sewn hanging sleeve method. Very easy to follow - you don't need to read Japanese. I would start with a 9 1/2in wide strip for quilts intended for shows, otherwise there's a risk the end result would be too narrow. The machine stitching will make a more permanent finish than a hand sewn hanging sleeve too, so perhaps not the method to use if you might want to take the sleeve off later, say for a bed quilt. But you could use the sleeve construction and machine basting and simply do the final stitching by hand - use the same method she shows for sewing down the sleeve ends.
