In so far as seam pressing, I agree with everyone; do whichever works best in the project at hand. What no one has mentioned and has me interested is your statement about not sewing from edge to edge but only sewing seam allowance to seam allowance. I have not heard about that, except in cases where one is making Y seams or mitering corners. In all other cases, I have always sewn edge to edge. Since I am a family-self-board taught quilter, is this something I have missed learning about as I went along? Can anyone enlighten me about this type of piecing in cases other than I have mentioned?
