Machine Needles, Jeans/Denim

Schmetz

Jeans/Denim needles for penetrating extra thick woven fabrics, denims, or quilts with with minimum needle deflection, reduced risk of needle breakage and skipped stitches.

That's what it says on the package. It means you will find sewing heavy fabrics much less frustrating if you use these needles in your sewing machine :-)
