3. Reinforce Stress Areas When sewing seams that will experience a lot of stress, such as corners of bags or harnesses, consider reinforcing them with additional stitching or bar tacking to enhance durability.

Bag making machines come in various types, each designed to produce different kinds of bags. Some popular types include flat bag making machines, drawstring bag machines, and shopping bag making machines. Each machine is engineered to cater to specific requirements in terms of size, material, and design. Over the years, technological advancements have made these machines faster and more accurate, thus reducing production time and increasing output.

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.

One of the biggest differences is in the motor. Heavy duty machines need to power through thick, layered, or dense fabrics without straining, so they have more powerful motors. Motors in heavy duty machines often range from 1 to 5 amps, while standard motors are usually around 1 amp or less. With the stronger motor, heavy duty machines can sew for longer periods without overheating or losing power. This makes them ideal for sewing operations like upholstery where seams need to go through multiple fabric layers.
