“The Jewel – an Edwardian Shetland Lace treasure that’s a demonstration of both the high artistry of design and the supreme fineness of spinning and knitting skills then. Shetland women famously knitted constantly, even when carrying dried peat – the local fuel of these treeless isles. Finest lace though, was only done at home due to its fragility : each hand spun hair-fine thread would be made into a two ply from wool plucked (‘rooed’) from the back of a sheep in summer. Today’s Shetland wool has many similar qualities but is not as finely spun commercially. However, there are many modern pure fibre yarns that can successfully be used today.”
