5. Adjustable Stitch Length and Width Different upholstery projects may require different stitch lengths and widths. An ideal sewing machine should allow you to customize these settings easily.
Additionally, sailmaker machines often come equipped with specialized needles designed for heavy-duty sewing. The needles used in these machines are robust and capable of piercing multiple layers of fabric, as well as withstanding the abrasive nature of materials often used in sail construction. Furthermore, many machines include adjustable stitch lengths and widths, enabling sailmakers to customize their stitches based on the specific requirements of each project.

2. Walking Foot A walking foot, or a feed dog system, can be invaluable when sewing fur and leather. This feature helps to feed the materials evenly through the machine, minimizing the risk of shifting. It works by moving the upper layer of the fabric in sync with the feed dogs beneath, which is particularly useful when working with slippery and bulky materials.
