Here's Mr. Hadi—one of the workers who makes canes for drawn-beadmaking. In the 2nd photograph, we see him working on a small onion-shaped gather of white glass with red stripes. He has used a tool to perforate the gather and slightly inflated it, and is now getting it hot enough to be drawn—pulled to a great length.

He does this without any assistance, spreading his arms apart as widely as possible, removing the length created, draping it onto the floor next to him, grasping the butt-end of the previous pull, and repeating until all the glass is used up. He did this about six or eight times. The first and last pieces of cane are (usually) imperforate, though the four-to-six pieces from in-between are expected to have a decent channel running through their lengths.

I received a piece of this cane.
