There are some specific things to consider when sewing leather. First and foremost, you need to choose the right needle. Leather needles are made of strong steel and have a wider point and a rounder body than regular sewing needles. This makes them better at going through leather without tearing it. You should also choose a strong thread that is suitable for leather, such as cotton or linen thread. When sewing leather, it's also a good idea to use a special leather overlock machine that is designed to sew leather. If you don't have access to such a machine, you can also use a regular sewing machine with a leather foot, which makes it easier to control the leather while sewing. When sewing leather, remember to use the leather foot and leather needles and make sure to tighten the thread properly so that the seam is strong enough to hold the leather together.
