Coats Seta Reale is a pure silk sewing thread that is made up of continuous filaments that are spun together to form a tear-resistant, glossy, slightly stretching sewing thread. Seta Reale is great for hand sewing and for machine work on silk and satin materials or also on other luxurious and glossy materials. This medium thick thread (Silk No. 30) is an especially good choice for decorative stitching and button holes.

The thread number (here 30), it should be noted, denotes how long a piece of thread weighing one gram will be in millimeters. This means that the thinner the thread, the higher the number.
