The primary advantage of using a walking foot is the improved fabric control it provides. When working with thick fabrics, the risk of uneven sewing increases due to the bulk of the material. A walking foot helps to maintain an even stitch length, minimizing the risk of puckering or distortion that can occur when multiple layers are sewn together.

Proper tension is essential when sewing leather. Before starting, spend some time testing your machine’s tension settings on scrap leather pieces. A balanced tension will yield clean and even stitches. It is also advisable to use a longer stitch length (around 3.5 to 4 mm) when sewing leather to prevent the material from perforating too much, which can weaken its structure.

2. Double-Needle Stitching Machines Suitable for heavier fabrics, these machines provide stronger stitching lines, increasing the durability of the bags.

Heavy canvas is typically made from 100% cotton or cotton blends, making it a dense and sturdy fabric. The weight of heavy canvas usually falls between 12 oz to 24 oz per square yard, contributing to its strength. This characteristic makes it suitable for various applications, especially in environments that demand resilience. Its natural fibers allow for breathability, which is essential for products used outdoors, such as tents, backpacks, and tarps.
