Three self-neatened seams include the French seam, the flat-felled seam, and the bias-bound seam. A French seam encloses the raw edges within a folded seam, providing a clean finish ideal for lightweight fabrics. The flat-felled seam features one seam allowance folded over the other and stitched down, creating a strong, durable seam commonly used in denim. The bias-bound seam encases the raw edges in bias tape, offering a neat finish while allowing for flexibility in fabric types.
