These wooden needles are made especially for tapestry weavers. They are large and simple to thread, even with sizable or highly textured materials. Their long length efficiently travels under multiple warping threads to make weaving faster and easier. These weaving needles come in three lengths - 12cm (4¾"), 17cm (6½"), 22cm (8½"). Any, or all of them will be an asset to your weavers tool belt.
