Double or twin needles are great for decorative stitching, hemming, and heirloom sewing. They’re my favorite go-to needle for hemming knits. Best of all double needles fit almost every sewing machine.

Double Needle Facts

  • Double needles fit any machine where the needle is threaded front to back not side to side.
  • Common double needles sizes include: 1.6, 2.0, 3.0, 4.0, and 6.0.
  • The sizing refers to the distance in millimeters between the needles.
  • Size 6.0 is too wide for some machines. If the widest zigzag stitch is 4.0 on your machine, do not use a 6.0. The opening in the throat plate is not wide enough for this extra wide double needle.
  • The bobbin thread catches both top threads, resulting in a zigzag look on the fabric underside.

Sewing Tips for Double Needles

  • Use two spools of thread on the top of the machine, position them so the threads unwind in opposite directions. This prevents the threads from tangling.

  • If your machine does not have two spool pins, wind an extra bobbin and stack the bobbin with the spool on the spool pin.

  • If the fabric between the double stitching “tunnels,” loosen the top tension.
