When referring to "Setting" pieces (usually a triangle) the term Setting is correct because they are used specifically for an on point quilt
setting or a specific block setting like square in a square. There are no Y seams (aka set in seams) used when attaching the setting triangles to the rows of quilt for making it on point or attaching the triangles to a square to make a square in a square block.
But when making a Lemoyne star that has Y seams then the term "set in" is used because the seams for attaching the corner squares and side triangles involves a Y seam (set in seam).
So Setting is the correct term depending on what procedure one is doing just as much as Set in is. They are two different techniques.
