Flatlock for Flat Seams

The flatlock forms loops on the upper side of the seam and stitches on the underside.

  1. Thread and set the machine for 2- or 3-Thread Flatlock.
  2. Sew two layers of fabric together (wrong side on wrong side).
  3. Carefully separate the two layers of fabric.
  4. The two fabric edges now lie flat on top of each other at the stitch width of the flatlock.
