What is seam allowance?

Seam allowance refers to the area between the edge of the fabric and the stitch line. This specific measurement is crucial in garment construction because it provides the necessary space for stitching that secures the fabric pieces together. A proper seam allowance ensures that the garment can be fitted correctly, allows for adjustments if needed, and contributes to the overall strength and durability of the seams.

In practice, the seam allowance must be calculated and cut accurately to achieve the intended design and fit of the garment. Different types of seams and sewing techniques may require varying seam allowances, but the concept remains consistent across various applications in sewing and fashion design.
