Most domestic sewing machines can be adapted for this technique by simply replacing the single needle with a double needle, typically ranging from 1.6mm to 4.0mm apart. The two needles are inserted into the machine just like a standard needle, but they must be used with a zigzag stitch or a straight stitch that allows for the dual-thread functionality. Additionally, it's crucial to use the correct type of thread and needle for the fabric being sewn, ensuring that the result is both visually appealing and structurally sound.

- In addition to the initial purchase price, buyers should also consider the long-term value of the machine.

- In addition to strength and durability, heavy duty thread is also designed to be thicker than regular sewing thread. This can be an advantage when sewing leather, as the thickness of the thread can help to create stronger, more visible stitches. This can give your finished product a more professional and polished look, making it more appealing and marketable.
Heavy duty machines typically have higher maximum sewing speeds, around 1500 stitches per minute, versus 1000-1200 stitches per minute for standard machines. Again, this allows them to work through heavy fabrics more efficiently. However, heavy duty machines also tend to sew better at slower speeds, in the 500-800 stitch per minute range, for optimal control through thick seams. So they provide a wider speed range to suit the fabric.
