  2. Grain • What is Grain? • All woven and knitted fabrics and some nonwoven fabrics have direction, or grain. The grain is determined by the position of the yarns and fibers in the fabric. • In woven fabrics, the grain must be made straight. Then pattern pieces must be cut out in the same direction as the grain if the garment is to hang properly. • Woven fabrics are constructed by interlacing yarns at right angles to each other. There are three grain directions.

  4. Lengthwise grain • The lengthwise yarns called Warp yarns, form the lengthwise grainin woven fabric. This grain runs parallel to the selvage edges of the fabric. • The Selvageedges are the finished edges of the fabric as it comes off the loom. • The lengthwise yarns are stronger than the crosswise yarns. They are used to pull the fabric through the loom. • The lengthwise grain usually runs in a vertical direction down the body.

  5. Crosswise grain • The crosswise grain is perpendicular to the lengthwise grain. It is formed by the crosswise yarns, which are called weft or filling yarns. • The crosswise grain tends to be weaker than the lengthwise grain. • The crosswise grain may have more stretch than the lengthwise grain. • Therefore the crosswise grain is usually going around the body.

  6. Bias • The bias runs diagonally across the fabric. True bias forms a diagonal angle and is at an exact 45° angle to the lengthwise and crosswise yarns of the fabric. The bias has a great deal of give.
