Why is it essential to iron seams during sewing?

Ironing seams during sewing is crucial for ensuring a crisp finish and the proper alignment of fabric pieces. When seams are pressed, the fabric lays flat, which helps to eliminate bulging or uneven areas that might otherwise disrupt the overall look of the finished garment. This flatness also aids in achieving accurate measurements, as misaligned or bulky seams can lead to difficulties when sewing additional components or when fitting the final piece.

Proper seam pressing can also enhance the overall structure of the garment, allowing for better shaping and definition. Additionally, if seams are pressed open or to one side as appropriate, it can help in reducing bulk in areas where multiple seams meet, providing a neater appearance. Therefore, pressing seams not only contributes to the aesthetics of a project but also plays a vital role in the technical aspects of garment construction.
