Thai silk begins with a cocoon. The silkworm spins one continuous filament, and that filament is reeled by hand rather than cut, so the thread keeps its length and its character.
It is slightly uneven. Small slubs and soft irregularities run through the yarn, the mark of a thread made by people and not by a machine. We think of those irregularities as honesty.
On the loom, the warp is held taut while the weft crosses it, pass after pass. The cloth is built from a pause and a return, repeated thousands of times. It is slow work, and you can feel the time in the fabric.
Raw silk keeps a little of its natural gum, so it feels dry and crisp at first and softens with wear. Black silk takes light differently from any other cloth: it does not shine so much as glow where it folds.
