Silk has long been prized as one of the worlds finest fabric. Nothing mankind has concocted comes close to the strength and softness of silk. Silk is even surprisingly insulating; have you ever noticed how the finest wool coats and pants are always lined with silk? When Yana or I notice affordable clean silk in the waste stream, we usually acquire it. Since silk is all natural, it can be composted; but this precious fabric shouldn’t be cycled through the chain of life until it is dirty and torn.
