How can you identify the grain direction on a fabric selvage?

• A. The warp threads run perpendicular to the selvage.
• B. The grain line runs parallel to the selvage.
• C. The warp threads run parallel to the selvage and the grain line is perpendicular to it.
• D. The selvage indicates print direction.

Answer: (C)

The main idea is that the grain direction in woven fabric is defined by the warp yarns, which run lengthwise along the fabric and are parallel to the selvage. The selvage edge is created by those warp threads, so you can identify the lengthwise grain by looking along the edge—the threads go in that same direction as the selvage. The crosswise grain, by contrast, runs perpendicular to the selvage. When a pattern has a grain line marked, it’s typically drawn parallel to the selvage to indicate the lengthwise grain. In short, follow the warp along the selvage to find the grain direction; the grain line on patterns should run parallel to that direction, not perpendicular.
