Description
These are standard industrial needles used for upholstery fabrics, vinyl and even genuine leather.
Sizes 21 and downwards are usually used for upholstery fabrics and vinyl. From size 22 and upwards is used for genuine leather and other thicker than usual fabrics and vinyls. This is just a size guide, please be prepared to test and find the right needle for your project.
A good rule of thumb is the thinner your material the lower the size number and the thicker your material the higher the size number.
