Bombyx Mori (or Mulberry Silk Moth) is the name for what is actually a caterpillar, not a worm. These little voracious eaters of Mulberry leaves, produce a single strand of fiber filament, when unwound can be up to 1,600 yards long. This explains silk's lustre, drape and strength. Silk has a memory; it can stretch up to 25% without breaking and return back. A good insulator because it does not conduct heat, silk keeps you warm in winter and cool in summer.
And fabulous looking and feeling, all year round!
