I used inexpensive, natural cooking twine. I don’t have an exact yardage, but I probably only used about one-third of the cone on size US 8 dpn’s.

I don’t think gauge matters on this--you’re just slipping it around a 6” glass bubble bowl. I tied off the top around a metal O-ring you find at a hardware store using a slip knot.

Pattern can be found here--link to PDF download is in the text above the last photo.
