Sewing & Pattern making Terms

Grain / Cross grain

When it comes to sewing and pattern making, understanding the grain and cross grain of fabric is essential for achieving the best results in garment construction. These terms refer to the direction of the fabric’s threads and play a crucial role in how a garment hangs, drapes, and stretches. In this article, we will explore the concepts of grain and cross grain and their significance in the world of sewing.

The Grainline: Establishing the Foundation

The grainline is the key reference line on a pattern that corresponds to the fabric’s straight grain. It runs parallel to the selvage edge and is typically indicated by an arrow on the pattern piece. Understanding and aligning the pattern’s grainline with the fabric’s grain is fundamental to ensure proper fit and maintain the intended design elements.

The Straight Grain: The Foundation of Stability

The straight grain refers to the threads that run parallel to the selvage edge of the fabric. It provides stability and structural support to the garment. When the straight grain is aligned correctly with the pattern’s grainline, it ensures that the garment hangs straight and maintains its intended shape.

The Cross Grain: Direction of Stretch

The cross grain, also known as the widthwise grain, runs perpendicular to the selvage edge. Unlike the straight grain, the cross grain has a bit of stretch or give. Understanding the direction of the cross grain is crucial when working with fabrics that have stretch, such as knits. It determines how much stretch the fabric has horizontally and helps determine the appropriate pattern layout and grainline placement.

Importance of Aligning Grain and Cross Grain

Aligning the pattern pieces with the appropriate grain and cross grain is vital for several reasons:

  • Fit and Hang: Proper alignment ensures that the garment hangs correctly on the body, following the natural contours and avoiding distortion.
  • Stability and Durability: Aligning the grain and cross grain correctly contributes to the garment’s stability, reducing the risk of stretching or warping over time.
  • Bias Draping: Understanding the grain and cross grain is crucial when working with bias-cut garments. The bias refers to a 45-degree angle to the straight and cross grains. Utilizing the bias grain can create beautiful draping effects, but it requires careful handling due to its inherent stretchiness.
  • Pattern Matching: Aligning fabric prints, plaids, or stripes requires careful consideration of the grain and cross grain. Matching pattern elements across seams or within design features contributes to a polished and professional finish.

Tips for Identifying Grain and Cross Grainlines

  1. Selvage Edge: The selvage edge is the finished edge of the fabric, created during the weaving process. It typically runs parallel to the straight grain and does not fray.
  2. Lengthwise Threads: The lengthwise threads run parallel to the selvage edge and correspond to the straight grain.
  3. Stretch Test: Gently pulling the fabric in different directions can help identify the direction of stretch, indicating the cross grain.

Understanding the grain and cross grain of fabric is a fundamental skill for seamstresses and pattern makers. By aligning patterns correctly with the fabric’s grainline and utilizing the appropriate stretch direction, they can achieve garments that fit well, hang beautifully, and showcase the fabric’s unique characteristics.
