Shuttles are among the most decorative of sewing accessories. In general shuttles began to emerge in the 17th century and knotting was a popular partime at court. Shuttles were between 2 and 6 inches long and were lavish, tortoiseshell, ivory and precious metal being popular, with all types of inlay and decoration employed. Similar shuttles were used for tatting - creating patterns in white thread similar to lace. Shuttles were manufactured in pairs, although elaborate examples are rare. Plain shuttles in bone and ivory are relatively common and still tend to be brought to use if the points are in good condition. At the other end of the scale decorated shuttles will be a significant addition to a collection with some running into thousands of pounds.
