Rowan's Scottish Tweed yarn from the Isle of Lewis in the Outer Hebrides is the jewel in Rowan's crown. And in this fantastic new book Sarah Dallas, joins forces with two colleagues from London's prestigious Royal College of Art - former student Catherine Tough and fellows teacher Wendy Baker - to create a singularly beautiful collection of sweaters, cardigans, accessories, throws and cushions, inspired by the soft colours and colour work traditions of the islands, but with a contemporary twist. These unique, softly marled pure wool yarns come in a range of weights - 4ply, double knit, Aran and Chunky - and combine to create exquisitely graded colour combinations.
