Sublime is a sister company to Sirdar
It produces their higher quality range of yarns.
Colours are more densly saturated into the fibres, the fibres are longer (worsted) which makes for a smoother look, the ply are in many multiples creating a much more rounded yarn and as such a higher definition to the stitch.Colours tend to be the most upto date with fashions and beause of this tend to be out before you will see them appear in clothing, upholstery and furnishing stores so you can have your pattern knitted up in time for the seasonal changeovers.
