This uniquely patterned strand of rondelle beads is made using traditional methods used to create powder glass beads. The procedure for making the beads consists of a number of steps whereby powdered glass is poured into molds of clay and baked in a specialized oven. Individual beads measure 4 x 10mm and have a hole size of approximately 2mm. You will receive a full strand measuring approximately 20-24 inches. Please note, some strands may not have raffia wrapping at the top.
