Nymo is a nylon thread, specifically made for beading seed beads. We recommend coating your thread with beeswax before beginning any seed or bugle bead project. It will keep the thread from fraying and help it last longer. Each 3-ounce spool of thread contains approximately 2,998 yards (8,994 feet). Spools will have a slightly heavier denier, bond and finish than the bobbins.
