This beautiful thread made by DMC has become very difficult to source. It has very little twist, resulting in a soft, silky thread which blends together effectively when used for surface whitework stitches such as satin stitch and trailing. Slightly heavier than one strand of stranded cotton, it provides an effective option for those who struggle with superfine threads for whitework. It is also my preferred thread for padding in whitework since it builds rapidly to give firm, accurate padding. It also takes dye very well.
