Natural Wool Yarn in a 100g (3.5oz) Hank / Sift for Embroidery / Tablet Weaving.
20/4 means 4 threads and 20 grams per metre, so each hank consists of a 4 thread yarn weighing approximately 100 grams (3.5oz) and around 500 metres (1640 feet) long.
Most are 100% wool, but some may be blended with silk / bamboo and range from off white to a light cream colour.
Natural wool is ideal for dying yourself, so select this if you want to dye your own wool.
