Schmetz Quick Threading Needles ~ Size 80/12, 5 needles per pack. Fits the Singer Featherweight 221 and 222 perfectly! The Quick Threading needle is a Universal needle with an easy-to-thread slot in the eye. Reduce sewing speed so the thread does not pop out of the eye. Avoid using sensitive fabrics, the slot may snag the fabric. Do not use it for quilting as the batting may pull. Not recommended for sewing denim, as the eye structure is too weak. Quick threading needles are compatible with wovens and knits, though be sure to test your fabric first. ------------------------------------------------------------------------------------ Needles of exactly the proper shape and of the very best quality are absolutely essential to good work with a sewing machine. If you still have original unused Singer brand needles in the little paper or plastic packages (typically made in the U.S.A., Great Britain or Germany) - as long as they are not rusted or bent from age - they are of the finest quality and you can use them with confidence. Newer Singer needles (made in Singapore, Brazil or the likes thereof), however, are not made to the same superior quality that they once were, which is why we use and recommend the Schmetz brand of needles for today’s modern sewist. The quality of Schmetz is comparably equivalent to the original Singer needles. Click here to download this antique booklet illustrating how a Singer Needle was madeby the Singer Manufacturing Company Below, you will find information that was taken from an old Singer Machine Sewing Teacher’s Textbook with updates for today’s sewing. Much of the information is still current and useful. A perfect stitch can be obtained only when the thread is selected to suit the fabric which is to be stitched and the needle is the correct size for the thread. If the needle is too fine for the thread and the material to be sewn, it is quite likely to break when crossing a seam. If a large needle is used on fine material, the perforations made by the needle will show on the finished work. A table of correct needles for the various sizes of silk and cotton is given in the table below, but may also be found in the instruction manual for each original Singer machine. This table should be carefully followed when ordering needles and when changing them for various classes of work.
