DIFFERENTIAL FEED
Fabrics That Stretch
Fabric: 3 pieces of ribbing,
5” (width) x 2” each (length)
Needle: 80/12 Universal
Thread: 4 cones of serger thread
Presser Foot: Standard
• Owner’s manual pg.___
• Thread the serger for a 4-thread overlock stitch.
• Fine tune the tensions for a balanced overlock stitch (3-5).
• Set the cutting width as needed and set the stitch length to 2.5mm.
• With differential set at N, serge two of the ribbing pieces together along one 5” edge.
If the fabric is stretchy enough you will have a wavy edge.
• Adjust the differential to 2.0.
• Stitching along the 5” side, serge the remaining ribbing to the other side of the piece,
trimming slightly. With differential at a higher setting, the the wavy edge should be eliminated.
• Mark the differential settings on the fabric sample.
• Compare the seams to see how the differential settings can affect stretching.
• Trim and mount the sample.
• Return the differential feed setting to N (normal).
