Oh, how funny!
I've learned so much in my life (so far!) and I've never known that.
Logical, though!

French Seam

One of the seam varieties in which all raw edges are enclosed.

Sew a quarter inch seam with the wrong sides of the fabric together,
trim closely, press the seam with the right sides of the fabric
together, sew a quarter inch seam, press to finish.

Very handy if you don't have a serger.
