These yarns are from Todd & Duncan of Scotland, and were sold by them under the brand name Harmony and used in some of the worlds most luxurious knitwear. Made from the best cashmere and silk fibres they are still soft but give better stitch definition and feel sleeker but also a bit crisper than the pure cashmere - and of course the silk gives extra brightness to the colours.

As 2/28NM these yarns give 2,300 yards per cone, 7,000 yards per lb.
