The measured distance between the stitching line and the raw edge of fabric is a critical component in garment construction. It provides extra material beyond the sewn seam, preventing fraying and adding strength. For instance, a common dimension for this measurement is 5/8 inch, frequently used in commercial patterns to allow for both sewing and subsequent finishing.
This extra fabric layer is fundamental for durability and longevity. It allows for adjustments during fitting, provides options for different seam finishes, and safeguards against the seam unraveling under stress or washing. Historically, the width of this allowance has varied depending on the era and the intended use of the garment, reflecting evolving tailoring techniques and material availability.
