1927 Breed Standard
In the early 1900s, demand for high quality hand knitted garments increased and knitters throughout Shetland adapted to satisfy that demand.
Their industry was then threatened by a reduction in wool quality - through cross breeding, to improve carcase quality.
In order to preserve the characteristics of the Shetland breed, the Shetland Flock Book Society was formed, on Shetland, in 1927 and its members drew up the Breed Description that is still in use today.
