Doubling and Throwing:

This step is optional. Silk without twist is often used in embroidery and weaving, and has a high luster.

To make a thicker thread, you can take two or more reelings and twist them together (called "doubling") on a spinning wheel.

"Throwing" involves taking two or more of those twisted threads, and twisting them together in the opposite direction.
