Hemline Sewing Machine Needles - 120/20

120/20 refers to two sizing systems. '120' is the European metric size, and '20' is the American size. This indicates a larger, medium-to-heavy weight needle.

These are universal needles and fit most standard home sewing machines. However, always confirm compatibility with your specific machine model.

A slight ballpoint tip is a rounded needle point that helps to push fabric fibers apart rather than piercing them. This is beneficial for knit fabrics to prevent skipped stitches and for some woven fabrics to minimize damage.

Needles should be replaced regularly, typically after every 6-8 hours of sewing, or immediately if you notice skipped stitches, thread breaks, fabric damage, or if the needle appears bent or dull.

While size 120/20 is robust, these are general universal needles. For consistent and easy sewing through thick layers of denim or leather, specialized denim or leather needles are usually recommended.

These needles are ideal for general sewing on medium to heavier weight woven fabrics (like cotton twills, drills, some linens) and a variety of knit fabrics.

Ensure the needle is fully inserted with the flat side to the back. Check if the needle is bent or dull and replace it. Verify needle compatibility with your machine and fabric type.

Check for burrs on the needle or sewing machine's hook. Ensure the thread is correctly threaded through the machine. Use a new needle if the current one is damaged or worn.

The needle might be too coarse for the fabric, or the tip may be damaged. Try a finer universal needle or a needle specifically designed for the fabric type (e.g., sharp point for wovens, ballpoint for knits).

The needle may be bent, inserted incorrectly, or the machine is hitting something. Ensure correct insertion, check for bends, and verify that the needle is aligned with the machine's path. Do not force the needle.
