about this she informed me that she's been doing it this way for a while. So ... in case I'm not the last one on the planet to figure this out ... here's to straighter seams!
I prefer larger backings and seam vertically when I can, but ... lately they seem to all come out better horizontally. I quilt them myself on my domestic machine.
This makes sense, and I understand what you are saying, however I have had the salvage edge shrink differently than the rest of the yardage. May I suggest after the seam is sewn to use your wavey/pinking blades and cut off the salvage, then iron seam open, will lay flatter for backing....IMHO
