Size AA C-lon beading thread is best for use with smaller 15/0 seed beads. Industry size Tex 35, each bobbin has about 75 yards of thread. It's the standard beading thread for peyote, square stitch, bead weaving on and off loom, bead stitching and embroidery with seed beads, and a better alternative than Nymo thread (Nymo was originally created for the shoe industry). Unlike C-lon cord, this thread does not have multiple plies, but it is exceptionally strong for its size and has a high resistance to abrasion. UV resistant and vat-dyed, the color does not rub off. Made in the U.S.A.
