Pro: Works Well on Curves

Felled seams are sturdy and utilitarian. We’re mostly familiar with them as the re-inforced seams on our jeans, but felling is a very old technique. It was a handworked finish for seams centuries before sewing machines were invented, and was often seen in traditionally home-made items like shirts and chemises. A seam allowance can be felled after the fact. It’s a good finish for both hand and machine sewn seams, and, properly done, is completely invisible from the outside of the garment.
