One of the key advantages of using a double needle coverstitch is its ability to provide a durable seam that won't easily unravel. Unlike standard sewing techniques that can compromise the integrity of the seam when stretched, the coverstitch uses a combination of straight stitching and chain stitching to absorb tension without breaking. This is particularly important in areas of a garment that experience a lot of wear and movement, such as armholes, waistbands, and hems.

When it comes to upholstery sewing, having the right needles is essential for achieving professional results. Needles for upholstery sewing are specially designed to handle the thick and tough materials commonly used in furniture making. Choosing the correct needle can make a big difference in the success of your project.
