Masuhisa Tussar Silk 1/5.3

柞蚕糸 Sakusanshi is tussar silk.

Tussar silk is made from silkworms that eat leaves other than mulberry (sawtooth oak, oak, chestnut, horse chestnut, beech, etc.). Unlike pure silk from silkworms that only eat mulberry, it is not pliant and shrinks when heated.

However, now that natural materials are being reconsidered, rusticity, hardness of thread, lightness, and unique luster characteristics in yarn that are gaining attention.
