Seaming Knit Fabrics:
Presser Foot Pressure
Thread the serger for a 4-thread overlock stitch, using regular serger
thread in the needles and Woolly Nylon in the loopers.
Set all thread tensions at usual 4-thread overlock settings.
Using a fabric marker, divide the fabric in half along a 6” side.
With right sides together and a ¼” seam allowance, serge to the mark
on the fabric.
Without removing the fabric from under the presser foot, notice the
“ripple” effect where the fabric has stretched.
Reduce the presser foot pressure to low.
Seam the jersey to the end of the fabric.
Remove the fabric from under the presser foot and observe the de-
creased “rippling”.
Return the presser foot pressure adjusting lever its normal setting.
Trim and mount the sample.
