What to Consider Before Buying a Sewing Machine for Leather?
Type of Leather Products
The first thing you should consider before purchasing a sewing machine for leather is the type of products you want to create. Are you looking to make garments, bags, wallets, purses, footwear, or something else? Knowing what kind of leather projects you want to take on will help determine which sewing machine is best suited for the job. 
The motor type and speed of the sewing machine is an important factor when it comes to leather sewing. Heavy duty projects like leather require a powerful motor that can go up to 1700 stitches per minute or more. This is why many people opt for industrial sewing machines as they are designed specifically for heavier fabrics like leather. 
The shuttle type of the sewing machine is another important consideration. Sewing machines come with two types of shuttles: rotary and oscillating. Rotary shuttles move from side to side while oscillating shuttles move up and down. Oscillating shuttle machines are designed for heavier fabrics like leather, making them a better choice for leather projects. 
The stitch length you choose will depend on the type of leather product you are sewing. For an everyday leather bag or wallet, a shorter stitch length is ideal as it allows for a tighter and stronger seam. However, if you are working with thinner leather products such as jackets or shoes, then a longer stitch length may be necessary to provide a secure seam. 
The lubricant used in the sewing machine is also an important factor to consider when selecting a leather sewing machine. This is especially true for machines that are designed to work with heavier fabrics like leather, as they require special lubricants that can keep the moving parts running smoothly and reduce wear and tear. 
Can Any Sewing Machine Sew Leather?
The answer to this question is yes, most sewing machines can sew leather. However, the quality of the stitch and the overall finish will depend on which machine you use.
When it comes to sewing leather, not all sewing machines are created equal. While some machines may be able to successfully sew through thin layers of the material without any problems, they may struggle when it comes to thicker layers of leather. This is where the Singer 15-91 Leather Sewing Machine excels.
This machine has been specifically designed for leather sewing, making it ideal for those who want to work with this material. 
Do I need a special sewing machine for leather?
Yes, you do. Leather is a tricky fabric to sew and it requires extra care in order to make sure your seams are straight and secure.

This machine is specifically designed for handling thick fabrics like leather.
