www.singersewinginfo.co.uk/needles/ will probably give you far more information on needles than you wanted. I buy unopened packs of needles in thrift stores whenever I find them, whether the name is singer, white, sears, kenmore, jc penney, etc. I have a box of 100 Singer needles made in Brazil, all size 90/14. So long as they are the standard type for the machine I am using, I don't bother with whether it says Singer or Kenmore, etc. I have ordered Organ needles on Ebay, seems they were referred to as Orange. Many times I open a box of vintage sewing machine accessories and will see a pkg. of Organ needles. I am aware that certain needles are best for certain tasks, such as for knits, sharps for quilting, etc. but as for information from Superior Thread, I figure they have a vested interest. When I buy from JoAnns, it is usually Schmetz jeans needles, but with my Thrift store finds, and ebay, there has not been a need for JA in a long time.
