Silk fabric made from a yarn spun from the short lengths of silk left over from long filaments, broken threads, i.e. waste, or the shorter lengths from broken or damaged cocoons, and sometimes both.
Spun silk fibres are soft with a good sheen and are often twisted for durability and light reflection. Used for passementerie and knitting, it is also woven into many fabrics and bedding. I personally like the slightly heavier, softer, less ‘formal’ hand of spun silk.
