Machine Sewing Needles -Ballpoint Jersey Size 90/14

The Jersey (Ball Point) needle has a rounded, semi-spherical ball point whose diameter is approximately 20% of the blade's diameter.  These needles are designed to alleviate making holes in knit or loosely woven materials.  The rounded tip slips between yarns rather than piercing them.  

Uses:  Knit and stretchy fabrics such as spandex and Lycra. 

A universal is sometimes better for finer knits.
