One of the most significant advantages of using a double needle is the ability to create professional-looking hems on knit fabrics. When sewing knits or stretch fabrics, a single line of straight stitching can sometimes lead to a lack of stretch, causing the seam to break. However, the double needle creates two parallel lines of stitching that can better accommodate the fabric's natural stretch, providing a durable and aesthetically pleasing finish. This makes it an ideal tool for sewing items like t-shirts, leggings, and activewear.

Handheld sewing machines typically offer basic straight stitch functionality. They lack the versatility of full-sized sewing machines, which can provide various stitch patterns and options. This limitation can be restrictive if you have more complex sewing projects in mind.

In the realm of industrial packaging, Flexible Intermediate Bulk Containers (FIBCs), commonly known as big bags, are essential for transporting bulk materials. The manufacturing of FIBCs involves various processes, among which sewing is critical to ensure the strength and reliability of the bags. At the heart of this sewing process lies the FIBC sewing machine head, a complex component that significantly influences the quality of the final product.
