Twine 7-ply 1 oz. (82 Feet) is a round construction, polyester twine used for hand sewing. The ply used depends on personal preference, but we recommend using 7-ply twine for sewing large rings. Use a #14 or #16 needle with 7-ply twine. The strands of a heavy ply twine can be unlaid to use for other purposes. This twine is not pre-waxed, be sure to order wax. Twine should be well waxed—this greatly increases its resistance to the elements and reduces the chafe involved in the sewing process.
Sailrite recommends using a lighter twine for hand sewing seams and smaller rings.
