Our artists always use linen thread for stringing beaded glass chains because of its superior strength and durability. Waxed linen thread is preferred by many artisans and sewers because the wax coating makes it extra durable, prevents fraying, and ensures that it doesn't stretch. When making bead chains, it's important to use a thread that will not stretch over time, because regular thread can lengthen quite a bit from the weight of blown glass beads. Spun from natural linen, this large spool has 6 ounces of 3-ply waxed linen thread. From Hungary.
