A double needle consists of two needle points attached to a single shank. It is available in various sizes and needle types, such as universal, stretch, and quilting needles. The choice of needle type should be determined by the fabric you are using. For instance, use a universal needle for woven fabrics and a stretch needle for knits.

1. Stitch Variety Professional upholstery sewing machines typically offer an array of stitches, including straight, zigzag, and specialty stitches. This variety enables upholsterers to create tailored designs and finishes, elevating the aesthetic appeal of their work.

When it comes to sewing heavy materials like canvas, having the right equipment can make all the difference. Heavy-duty sewing machines are designed to handle the thickness and toughness of materials such as canvas, leather, and denim. These machines are not only built to withstand the rigorous demands of heavy fabrics but also provide the precision and efficiency needed for a variety of sewing projects.

However, like any tool, handheld leather sewing machines come with their own set of limitations. They may not match the speed or power of a traditional sewing machine, especially when it comes to larger or thicker materials. Consequently, while they are perfect for small projects and quick repairs, crafters may still need to rely on more robust machines for larger tasks.

This is particularly beneficial when working with fabrics that are prone to stretching, such as jersey or spandex. The stitch can accommodate the movement of the garment without breaking or causing stress on the seams.
