What is the 45-degree angle across the fabric surface called?

Explanation:
Understanding fabric grain directions is essential. In woven fabric, the warp runs lengthwise and the weft runs crosswise. The straight grain is aligned with the warp, extending along the length of the fabric parallel to the selvage, while the crosswise grain follows the width. The line that crosses the fabric at about a 45-degree angle to both warp and weft is called the bias. The bias runs diagonally across the fabric and offers the most stretch and drape because the yarns aren’t aligned with the fabric edges. This makes bias cuts ideal for garments that need to curve smoothly and for bias binding, which benefits from that extra flexibility.
