Thread shows through at stressed seams


Stitching Smiles


Serger Stitching Smiles image


















Stitching smiles on serged seams are common when using knits. The areas that receive stress like the crotch or butt, or sometimes the sides of the waiseline seams, start to "gap" or "smile" under pressure.

The easiest ways to avoid this:

1. using matching thread color in the left needle helps reduce the visibility of stretched seams

2. tighten the left needle tension as best as you can when serging the first time, and then

3. either serge a second time, with the KNIVES DISENGAGED, or sew a straight seam with a sewing machine.

Many folks find this issue or stitches coming actually unravelled when they serger across an already serger seam going the opposite (perpendicular) direction.  


One suggestion is to reinforce the seam with a regular sewing machine.
