Hemline Sewing Machine Needles - Jeans - 100/16

These needles are specifically designed for heavy fabrics such as denim, heavy twill, workwear, canvas, and dense linens.

It refers to the needle's thickness. 100 is the European sizing, and 16 is the American sizing for needles. Both indicate a thicker needle suitable for heavier materials.

While they can technically sew through cotton, they are overkill and may create unnecessarily large holes. It's best to use a universal needle or a fine-point needle for standard cotton fabrics.

It's recommended to change needles after every project or every 6-8 hours of sewing, especially when working with tough fabrics, to maintain sharpness and prevent issues.

Yes, they are compatible with most standard home sewing machines that accept universal shank needles. Always check your machine's manual for compatibility.

These needles have a very sharp point and a stiffer shank. This design helps them penetrate dense fabrics easily and resist bending or deflection, which standard needles might not handle as well.

Ensure you are using the correct needle size for your fabric. Check that the needle is inserted correctly and that your sewing machine is threaded properly. Avoid forcing the fabric; let the machine and needle do the work.

Verify the needle is not bent or dull. Ensure it's inserted all the way and correctly oriented. Check your machine's tension settings and ensure the thread is not frayed.

The needle point may be dull or the fabric might be too delicate for this needle type. Try a finer needle for lighter fabrics. Ensure your machine's stitch length and tension are appropriate for the material.

This needle is designed to be stiff. If you are experiencing deflection, ensure the needle is fully inserted into the machine clamp. If the issue persists, check if the machine's needle bar is aligned correctly.
