Four Serging Techniques
3. Serging corners
For an outside corner, serge one or two stitches past the end of the corner, raise the presser foot and gently pull the thread tail off the stitch finger. Turn the corner and put the edge of the fabric right up to the needles. Pull up on the threads above the tension to get rid of any "thread slack," lower the foot and serge the next side.
The inside corner is stitched by straightening the corner. Make a 1/4 inch clip diagonally into the corner. Straighten the inside corner as you skim the fabric edge.
4. Serging Curves
An outside curve is hard to pivot around because the long presser foot holds the fabric. As you come around the curve, lift the presser foot and move the fabric from underneath the foot. Lower the foot and stitch a little more. Repeat as needed to complete the curve.
To stitch an inside curve straighten the curve out as you stitch.
