NYSTCE Family and Consumer Science (072) Practice Exam

How a pattern piece is oriented on fabric is determined by the grain line arrow. This arrow marks the grain line, which should run parallel to the fabric’s warp direction—the lengthwise threads that run from edge to edge and align with the selvage. Placing the grain line parallel to the warp ensures the piece hangs correctly, drapes properly, and retains the intended fit. The selvage is simply the fabric edge and isn’t a placement guide. Darts are shaping details and don’t indicate how to lay out the piece on the fabric. The warp refers to the lengthwise threads themselves, not a layout cue, so the grain line arrow is the correct indicator for aligning with the warp.
