Making of Dupion silk: Caterpillars create silk by secreting two rows of liquid from the top of their heads. When it touches the air, the liquid becomes solid and the caterpillars wrap themselves up in this substance forming a cocoon. Two caterpillars in the same pod wrapping their yarns around each other yields a double strand which gives a thick and thin appearance. This textured fabric is known as Dupioni silk.
Dupioni silk has an irregular weave with tiny nubs showing. It is sometimes confused with 'shantung' which is usually lighter in weight and has a finer weave than Dupioni. Dupioni is used extensively by many of the top bridal designers and manufacturers, as well as drapery designers.
Please be aware that silk is a natural product and therefore will always have a small amount of natural flaws. For this reason it is always advisable to order a little bit more than you actually need
