The grain line on pattern pieces should align with which fabric direction to ensure proper drape?

• A. Align with selvage
• B. Align with nap
• C. The direction of the fabric's grain (warp) and how to align the piece with the fabric
• D. Align with the design on fabric

Answer: (C)

When you cut a pattern, line the grain of the pattern piece up with the fabric’s straight grain—the warp direction. The warp runs lengthwise and is the most stable thread direction, so aligning the piece with this grain gives the garment proper drape and hangs correctly. If you cut on the cross grain or bias, the fabric can stretch and distort, causing uneven hems and seams. For fabrics with nap or directional patterns, you still align pieces along the warp for consistency in drape, and then handle the nap or print direction separately to keep shading uniform. The selvage runs parallel to the warp, so aligning to the selvage echoes the same grain direction, while aligning to the design or print alone can lead to mismatched drape or color variance.
