When pressing seams open they are more likely to be even when using the 1/4 in seam, especially if you use a presser foot with a guide on it. When pressing to one side due to the "thickness" of the cottons and if the seam is not exactly a "scant", you have a bump over 2 layers of material when pressed. Trying to figure out the "scant" has been trying but I am getting closer, I think? I recently read of a quilt designer/maker returning to the open-pressed seams because of all the problems with the "scant". I think a "scant" is in the "eye of the beholder".....just a thought... (sorry to be lengthy)
Perhaps I am not understanding you, and if so, please forgive me. Aren't you going to have the 'bump' of two (actually 3) fabrics, regardless of whether your seam is a 'scant' one or not, when pressed to one side?
That said, I usually press to one side unless I have a need to press seams open.
Yes, you are correct about the 3 layers. Even so, logically it all makes sense. My bad... Sorry.
