Weavers can use the pure silk threads to make fine tapestries. I found an ancient example for it, a french antique on from the middle-ages. You can see here:
"Made of wool, silk, and gilded-silver, these designs were based on
fifteenth-century engravings and were part of a series produced by an
unknown manufactory in Paris around 1660. While exploring the allegory
of Psyche as told in the second century Latin novel Metamorphoses,
this installation addresses the history and use of tapestries through
its narrative reinterpretation during the Renaissance and Baroque eras."
You can see this tapestry in the Wadsworth Atheneum Museum of Art in Hartford, USA.
