Chapter 2:
Two-Thread Wrapped Edge
Overlock (narrow and wide)

Two-Thread Wrapped Edge Overlock (narrow)
The Two-Thread Wrapped Edge Overlock provides an elegant fine finish to lightweight
fabrics. When using clear threads in conjunction with the Two-Thread stitch, the
fabric appears to have an invisible edge. This gives a couture effect and looks
beautiful on finer fabrics. The Two-Thread Stitch requires the lower looper thread and
one overlock needle thread. The lower looper thread wraps around the fabric’s edge.
There are 2 different ways to set up for a Two-Thread Wrapped Edge Overlock stitch.
For a more narrow stitch (4.0) select the right overedge needle; for a wider stitch(6.0)
the left overedge needle is used.
