Serging seems like a waste of thread to me. I trim my quilts, then sew the binding on and that could be to the front or the back. Turn the binding and machine stitch. Sometimes it is a decorative stitch and sometimes a straight stitch. I like my bindings full and I do not care for hand stitched bindings at all - I don't care how good you are. It looks unfinished to ME. But, that is my personal opinion.
The nice thing about this hobby is we can all do it our own way.
