Silk. Spun by the silkworm Bombyx mori. Fed on mulberry leaves. Each cocoon yields one continuous filament, up to a mile long. We use 100% mulberry silk, 19 momme, undyed. The color you see is the color the worm made.
Linen. Grown from the flax plant Linum usitatissimum. No irrigation needed. Rainwater alone. We use 100% natural linen, undyed and unbleached. The color you see is the color the field grew.
