What to Consider Before Buying a Sewing Machine for Leather?

Type of Leather Products

When choosing a leather sewing machine, it’s important to consider the type of leather products you want to make. The Singer 31-15 is a great choice for small and medium projects such as bags, purses, wallets, or belts. It can stitch through thick leathers up to 8 ounces with ease due its powerful motor and adjustable presser foot. If your project requires tougher fabrics like upholstery leather or heavier weight leathers, you may need to consider an industrial strength machine. [2]

Motor Type

The Singer 31-15 is equipped with a powerful motor that can handle the toughest of leathers. It has been built to last and offers customizable settings for stitch length, width, and tension. This machine also features an adjustable presser foot that allows you to easily switch between different types of leather fabrics without having to adjust the settings manually. [2]

Can Any Sewing Machine Sew Leather?

Yes, any sewing machine can sew leather. The important thing is to choose the right needle and thread for the job.
