These sewing machine needles by Hemline have been specially heavy weight fabrics including denim, heavy twill, work-wear and densely woven fabrics such as canvas and heavy linens.
They have a very sharp point and a stiffer shank to help resist deviation from being able to sew a straight stitch on thicker fabric.
They can be used in most standard sewing machines.
Needle size – 90/14 and 100/16.
