Step 1: Understanding the Concept:
Before cutting pattern pieces from a fabric, the grainline of the fabric must be straightened.
Straightening ensures the warp and weft yarns are perpendicular to each other.
If the fabric is off-grain, the finished garment may warp, twist, or drape unevenly.
Step 2: Detailed Explanation:
Let us evaluate each method for establishing a straight crosswise grainline:
- (A) Cutting along the pulled crosswise yarn along the width: Pulling a single weft (crosswise) thread across the width of the fabric creates a visible line.
Cutting along this line ensures the cut is perfectly parallel to the weft yarns. Thus, (A) is correct.
- (B) Tearing the fabric across its width: For firmly woven cotton and linen fabrics, tearing across the width naturally follows the path of a single weft yarn.
This is a fast and accurate way to find the straight grain. Thus, (B) is correct.
- (C) Cutting the fabric along the woven stripe in the fabric: If the fabric has a woven stripe or plaid pattern, the stripes are woven along the warp or weft threads.
Cutting along this stripe aligns the cut with the grainline. Thus, (C) is correct.
- (D) Cutting along the crosswise fold of the fabric: The commercial fold of a fabric is often skewed, bowed, or off-grain during rolling at the mill.
Cutting along the fold without checking the grain will result in an off-grain cut. Thus, (D) is incorrect.
Therefore, only methods (A), (B), and (C) are correct.
Step 3: Final Answer:
The correct methods for straightening fabric are cutting along a pulled yarn, tearing the fabric, and cutting along a woven stripe, corresponding to option (A).
