Black 2mm Satin Cord, equivalent to a size 1 (standard) rattail cord. This glossy satin-like nylon cording knots well, is excellent for Kumihimo, and our internal testing indicates that it is colorfast! The ends can be sealed nicely with flame or with a thread burner. If adding beads, you can create a needle by adding a drop of glue and then rolling the tip to a point. It is not recommend to use jump rings on this type cord, as they can cause the finish to snag.
