The threads of the cloth are called the warp and the woof. The threads running lengthwise are the warp, those running across from selvedge to selvedge are the woof; both can be easily seen on a piece of coarse crash. The warp is usually stronger than the woof, and for this reason, any part of a garment requiring strength, should be cut lengthwise of the cloth.
Cloth is woven straight, but is sometimes drawn out of shape by pressing. When you can ravel a thread the width or length of the cloth, it is straight, or will become so after washing. If it looks uneven, it can be drawn into place by stretching it on the bias. Calico, when torn, often looks very uneven, and should be pulled into shape.The selvedge of cloth is the finished lengthwise edge, and cannot be ravelled. The raw edge is the edge that is cut or torn. A fold is the edge made by doubling one part of the cloth over the other. The nap is the shaggy substance on the surface of the cloth. To tear a piece of cloth, cut in one inch by a thread, then, holding a corner of the cut between the thumb and forefinger of each hand, roll the edges from you, and tear steadily; a fine piece of cloth must be torn carefully
