Prym Jersey Sewing Machine Needles - Size 70

Jersey needles have a medium ball point that parts fabric fibers without cutting them, ideal for knits. Universal needles have a sharper point and are better suited for a wider range of woven fabrics and some lighter knits, but can cause skipped stitches or damage on stretchier materials.

While they might work on very thin cottons, these needles are specifically designed for elastic fabrics like jersey. For standard woven cottons, a universal needle or a sharp needle would be more appropriate to prevent potential damage or suboptimal stitching.

It is recommended to change your needle after approximately 6-8 hours of sewing time, or immediately if you notice any signs of damage, such as skipped stitches, bent tips, or fabric snagging. Regular replacement ensures consistent sewing quality.

Size 70 refers to the needle's diameter. It is considered a fine needle, suitable for lightweight to medium-weight fabrics. Smaller numbers indicate finer needles, while larger numbers indicate thicker needles.

Yes, these needles are designed to work with standard household sewing machines, which often include needle threading aids. The needle itself is compatible regardless of whether your machine has a built-in threader.

Size 70 is generally for lighter to medium-weight knits. For very thick or bulky sweater knits, you might consider a slightly larger needle size (e.g., 80 or 90) with a ballpoint tip, depending on your machine's capabilities and the specific fabric.

Ensure the needle is fully inserted and correctly oriented. Check that the needle is not bent or dull; replace if necessary. Verify that the correct needle type (jersey ballpoint) is being used for the fabric. Check machine tension and ensure the thread is properly seated in the tension discs.

Confirm you are using the correct needle size for the fabric weight. Ensure the needle plate hole is not damaged. Try using a new needle, as a slightly burred tip can cause snags. If the issue persists, check for burrs on the needle plate itself.

Ensure the needle is correctly inserted and tightened. Verify that the needle is not bent. Check that the fabric is not too thick for the needle size, or that there are no obstructions (like pins) in the fabric path. Ensure the presser foot is correctly positioned and the machine is timed properly.
