I’ve seen many flat-felled seam tutorials around the web, but sadly not one of them mimics industrial flat-felled seam.
When
you look at the flat-felled seams on your store bought jeans you see

been nicely tucked between two details on the outside and on the inside
and the back center is right between those two rows of stitches.
And here is how you can do same looking flat-felled seam at home on your commercial sewing machine.
