Knotting, looping and netting
A netting gauge is a smooth, well-rounded stick with a uniform thickness throughout its length, so that the loops knotted around the stick are of equal size and easily slip off. The size of the gauge thus determines the size of the mesh. Gauges may be made of bone, ivory, steel or wood. It is also known as a netting mesh.
A shuttle is a boat-shaped device used to carry thread. With respect to decorative needlework, shuttles are used for netting and tatting. Shuttles for decorative needlework are made of a variety of materials, including bone, ivory, metal, plastic, tortoiseshell and wood. They are usually made of three elements: top, core and bottom (the top and bottom are normally identical) and are of varying sizes.
