A grain of fabric refers to the direction of the threads in the fabric. Fabrics have three grains: lengthwise grain (parallel to the selvage edge), crosswise grain (perpendicular to the selvage edge), and bias grain (45-degree angle to the lengthwise or crosswise grain). Each grain behaves differently when fabric is cut or manipulated.
Cross grain means running across the regular grain of a piece of wood.Cross grain or crosswise grain in fabrics means that the fabric grain has more stretch than lengthwise but less than bias.
The fabric for garments is cut in a way that will create the best lay when constructed. Fabric tends to stretch along the grain, which is why abutting seams are typically both cut along the grain.
lengthwise, lengthways
For sewing pattern layout, folds are made along the grain line. Lengthwise center fold would be folding the fabric with selvages together. Crosswise centerfold is folding the fabric at the crosswise grain, that is along the weft threads from selvage to selvage.
