With use over time, needles become dull, bent, damaged or can get misshapen eyes through normal wear. A damaged or worn needle can result in broken or shredded threads, skipped stitches, puckered fabrics and even damage rotary hooks—all of which contribute to frustrating thread breaks and a frayed look on your finished embroidered.
The solution? Don't wait until the needle breaks to change it. When starting a new project, use a new needle. Or, change the needle after every 8 to 10 hours of sewing time. Replacing your needles regularly is one of the easiest fixes, and can be easy if using a needle gripper.
