We recommend NYMO thread which is ideal for beadwork because it is more durable than cotton thread. OO is the finest weight threads, while D is the heaviest. OO is most commonly used for delicate jewelry making with small beads (12/0 or 13/0) and has 140 yards per bobbin. For general beadwork, B is used with 12/0 or 13/0 beads and has 72 yards per bobbin, and D is used with 11/0 or 10/0 beads and has 64 yards per bobbin.
