Differential Feed:
Fabrics that Pucker
Thread the serger for a four thread overlock stitch. Fine tune tensions
for a balanced overlock stitch. Adjust the stitch length to 2.5mm.
With differential set at N, serge on one 6” edge. If fabric is lightweight
enough you will have a puckered edge.
Adjust the differential to 0.7.
Serge along the other edge, trimming slightly. With a low differential
setting, the puckered edge should be eliminated.
Mark the differential settings on the fabric sample.
Trim and mount the sample.
Return the differential feed setting to N (normal).
