Boston...you don't sound stupid at all. I never knew the technique by that name. The name I know the technique by is called a y-seam. It is where two pieces of fabric meet like a Y and the 3rd piece is joined by sewing down one side and pivoting to join the other side. The technique you used (cutting the triangles off on the edge) in your braid quilt is what I have done, too. If you didn't cut the triangles off, this is the Y-seam that you would sew the next braid to. It's definitely easier to just cut for a straight edge to assemble. Your quilt looks great!! Really pretty the way you designed this..
