Sulky 40 Wt. Rayon thread has the same luster and soft, warm, natural look as silk with silk’s smoothness, but it is stronger than either silk or cotton thread of the same weight. It doesn't fray, fuzz or shrink and it has less stretch than Polyester. It's light-weight, color-fast, long-lasting, sturdy and washable.
