I am embarrassed to say that I never gave much thought to the type of needle I used when doing machine embroidery or sewing for that matter. My philosophy was – if the needle breaks, then replace it.
A sewing instructor once advised that if your thread breaks three times, it’s probably a pretty good indication that your needle needs to be replaced. Great advice. But that was the limit to my sewing needle knowledge.
As I have begun doing more embroidery on knit fabrics I have learned of the importance of using a ballpoint needle when working with knit fabrics. A regular needle is designed to pierce the fabric, but a ballpoint needle spreads the fibers away from one another keeping the knit structure intact. Using a ballpoint needle on knits improves the look of your design when embroidering on knit fabrics.
