I was always taught to use a ballpoint needle for knits and to use a sharp needle for woven fabrics. The Universal needle is suppose to cover both, but many are finding skipped stitches from using this for machine quilting. With the many layers of fabics and battings the universal needle isn't the right choice. A sharp needle mainly a denim or topstitching needle will go through the many layers and for a complete stitch. The needle is under a lot of pressure to pierce the layers and the universal needle is blunt enough not to go through all the layers especially at an intersection where seams are pressed in one direction. Hope this sheds some light on the problem and can say a lot of frustrations. Chris ps. Click on it twice and then save to you documents to see larger if you need to.
