Which term describes the lengthwise direction of fabric used to align pattern pieces with the grain?

• A. Bias
• B. Warp
• C. Weft
• D. Grainline

Answer: (D)

Grainline is the guiding line on a pattern piece that shows how to place it on fabric so it runs along the fabric’s lengthwise grain. The lengthwise grain corresponds to the warp threads that run parallel to the fabric’s length, and aligning the pattern piece with this grain keeps the garment from twisting or stretching oddly as you wear it. Weft refers to the crosswise threads, which run perpendicular to the warp, and the bias is a 45-degree angle to the grain, which changes how fabric drapes. So the grainline is the specific term used to indicate alignment with the grain on the pattern.
