Final answer:
Machine sewn seams offer advantages like increased speed, consistency of stitches, and greater durability compared to hand sewn seams. They also provide a variety of stitch types to suit different fabric types and uses.
Step-by-step explanation:
The main advantages of a machine sewn seam over a hand sewn seam include speed, durability, and consistency. Machine sewing is much faster than hand sewing, which can be critical for projects with tight deadlines or for those in a production setting.
Sewing machines are also able to create a stronger seam due to the uniformity of their stitches, which are tighter and more consistent than those typically achieved by hand sewing.
Furthermore, the durability of a machine sewn seam is superior, making it ideal for items that will endure frequent use or washing. Machines also allow for a variety of stitch types which can be selected to best suit the fabric and purpose of the garment or item being sewn, enhancing the seam's appearance and function.
