The Mỹ Sơn Sanctuary in Quang Nan Province is the closest example similar to Cambodia's Angkor Wat and it is only a short ride (south-west) from Hoi An. We hired a car (driver) and an English-speaking guide (a teacher) for the day. It was well worth the day's excursion.

Our guide helped us identify and understand the Hindu symbolism and mythology shown in the architectural designs and motifs.

Known as the religious and political capital of the Champa Kingdom and is one of the most significant Cham sites in Vietnam.

Drawing spiritually from Hinduism, the Cham built temples to honour Hindu divinities with fired brick, stone pillars and sandstone bas-reliefs.

My Son was initially constructed in the late 4th century, built by King Bhadravarman for the god Shiva (the creator, destroyer and preserver). From then on the temples were continuously developed until the 13th century. Okay, I had to look that one up!
My dumbing it down interpretation of Silk ...

The silkworm creates silk. By building its cocoon, it secrets a long continuous fiber too surround itself in. I was told, that the final secreted fiber is created by the combination of twin filaments and sericin (which cements the two together). Each has a usable length of about 600 to 900 meters (2,000 to 3,000 feet).
The final fiber is freed by boiling the cocoon which softening the sericin (the glue). Next is the task of locating the filament end and unwinding, or reeling, the filaments from several cocoons at the same time, sometimes with a slight twist, forming a single strand. The guide told me that the end of the fiber is easy to find because it floats away from the cocoon.

Several silk strands, each too thin for most uses, are twisted together to make thicker, stronger yarn. This process called throwing, produces various yarns that become specialized according to the amount and direction of the twist imparted.

Silk containing sericin is called Raw Silk.

Spun silk is made from short lengths obtained from damaged cocoons or broken off during processing, twisted together to make yarn.
Silk is sometimes treated with a finishing substance, such as metallic salts, to increase weight, add density, and improve draping quality. This is called weighting.
Why buy silk? Because it's affordable in Vietnam..lol
Silk does not readily retain soil!... who knew!
It has good strength, resisting breakage!
Silk is lower in density than cotton, wool, and rayon and is moisture-absorbent, retaining as much as a third of its weight in moisture without feeling damp, and it has excellent dyeing properties. It is more heat-resistant than wool! Awesome!
The down side.. Silk loses strength over a long period of time without appropriate storage conditions and tends to decompose with extensive exposure to sunlight but is rarely attacked by mildew and is not harmed by mild alkaline solutions and common dry-cleaning solvents; and imparts a static charge, especially in low humidity. Dam!
I thought of using it on the boat!
