For many years sewing was distinguished from stitching, in that sewing involved joining groups of leaves or sections to each other, gradually building up a complete text block; whereas stitching involved uniting the entire group of leaves or sections from front to back through the entire thickness of the text block, as in JAPANESE SEWING or side sewing. Both types, however, involved the use of thread. Today, on the other hand, sewing is considered to be construction of a text block by means of thread, while stitching is done by means of wire staples.
