Zephyr yarn is an American brand name for Berlin wool or German wool, used from the nineteenth century onwards. The vivid colours and soft, light texture ('light as a breeze', hence the name zephyr) made the wool very popular in Europe and North America and aided in the popularity of Berlin wool work.
