Sewing is stitching cloth, leather, furs, or other materials, using a needle and thread. Sewing can be done on a sewing machine, or by hand.
"Plain" sewing is mostly done to make or mend clothing and household furnishings such as curtains, sheets, upholstery, and table linens. It is also used for sails, bellows, skin boats, banners and other items shaped out of flexible materials.
"Fancy" sewing is done to decorate materials, such as embroidery or quilting.
Other places where sewing is done are stitching cuts in skin, making shoes, and making books.
