Does an interior seam edge need to be serged?

Question

I'm making bibs, which is a simple pattern of 3 layers of fabric sewn together and turned right side out. I always serge my edges, but I'm wondering if I can skip this step since the edge is going to be inside the bib. If I don't serge it, will it fray and cause a hole when washed over time? I'm using all cotton fabrics: flannel, chenille, and gingham.

Answer 1

after you turn it, are you going to top-stitch? if so then you won't have to worry about the seam fraying

Answer 2

You could always stay-stitch if you are worried about fraying. It will be quicker and less bumpy than serging.
