Grainline and fabric direction
What you are trying to accomplish
Preserve the direction in which each piece should be placed on the intended fabric.
Why it matters
Fabric direction affects stretch, drape, twisting, pattern matching, and appearance. On woven fabric, the straight grain usually runs parallel to the selvage. Bias and cross-grain behave differently. Nap, pile, directional prints, stripes, checks, and stretch can add further constraints.
Step by step
- Find the original grainline, center line, fold line, or placement instruction.
- Confirm which fabric type and direction the pattern expects.
- Add the grainline deliberately between two points in PatternForge.
- Keep it clear of labels and other markings.
- For a fold piece, verify that the fold edge represents the intended direction and symmetry.
- Record directional-print or nap requirements in the instructions when relevant.
What success looks like
The direction mark is visible, unambiguous, and faithful to the source. A sewist can align the piece without guessing which end points upward or whether pieces may be flipped.
Common problems and recovery
- No direction appears on the source: consult the original instructions or patternmaker; do not infer it only from screen orientation.
- The piece twists in a test garment: inspect grain placement and balance before changing width.
- Fold line and grainline conflict: confirm which line is authoritative for that piece.
- Directional fabric was ignored: update cutting instructions and layout constraints before release.
Quick safety check
Rotate the screen mentally: would the direction still be obvious if the piece were printed alone? If not, strengthen the label or instruction.
