Schmetz Twin Needle ~ Size 4, 0/90, 1 twin needle per pack.
A twin needle does NOT fit a Featherweight.
Double or Twin Needles are not suitable for sergers! Please use them only in home sewing machines. When using a Twin Needle, always use the zigzag needle plate with the elongated aperture. When using decorative stitches, the stitch width must NOT exceed the aperture because, otherwise, the needles will touch the needle plate and break. Try this out by doing the first stitches by moving the hand wheel manually. Additionally, the needle thread tension should be loosened when using Twin Needles.

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.
