Which technique allows for proper shaping in the garment by applying pressure and heat?

The technique that allows for proper shaping in a garment by applying pressure and heat is pressing. This method involves using a hot iron to shape seams, darts, and other areas of a garment, helping to create a tailored and professional appearance. When fabric is pressed, the fibers relax and take on a new shape, reinforcing the desired structure of the garment. This is particularly important for achieving clean edges and defined shapes, which are essential in high-quality sewing.

While ironing is related, it generally involves smoothing out wrinkles in a fabric rather than shaping it. Stitching refers to the act of sewing two pieces of fabric together, and while snipping can help reduce bulk or ease in fabric, it does not involve heat or pressure to achieve shaping. Therefore, pressing is the most effective technique for applying heat and pressure to shape garments properly.
