Seed beads are mainly made of glass and are the most widely used beading material. Bugle beads are commonly known as Nalki or Pipes in India. They are used in making jewellery and are also embroidered on high street garments - from stringing and bead embroidery to weaving and more. Pipe beads are used to create intricate embroidery designs and jewellery strands. They are made by cutting glass tubes in imported machines in long cylindrical shapes.
