The procedure in making seams involves preparing, stitching, and finishing two pieces of fabric so they are securely joined together. It begins with placing the right sides of the fabric together, aligning the edges, and holding them in place with pins. The seam line is then followed when sewing the fabric using a sewing machine. After stitching, the seam allowance is trimmed or clipped if necessary. The final steps include pressing the seam properly and applying a seam finish to prevent fraying and to give the garment a neat and durable appearance.
