Prof David Flynn JP from Belfast Northern Ireland:

As a regular sewer I purchase my Schmetz needles 80/12 by the 100. I change my sewing machine needles on a very regular basis especially when I am producing quilts, and can take their toll on a needle going through 3 layers of fabric. I always use this brand as I find them most reliable and I don't have problems with thread breaking or shredding. I have used other brands but keep going back to Schmetz.
