Sprang is an ancient method of cloth production. The earliest evidence of humans creating cloth are imprints on pottery shards found in Danish and Norwegian peat bogs dating from 1500-1100 BCE. The method of construction used to make the cloth that made these imprints is thought to be a technique known as ‘sprang’. This technique is worked on a frame. Threads are aligned parallel to each other, and in the simplest form, each thread winds around the thread to the right, and then the thread to the left. The result can look like the pattern in a chain-link fence. Cloth made using the sprang technique demonstrates amazing lateral stretchiness, and easily returns to the relaxed position.
