The idea is that a seam running vertically will cause a bump down the center when rolled onto a frame, and that causes the backing to sag on either side. I haven't had an issue with the "sagging"...it's there, but hasn't caused an issue.
That said, about two years ago, I started trying to have my seams run horizontally...no sagging at all & the selvage edge is what gets pinned to the leaders...and those selvages make it easy to be sure the backing is straight on the frame.
Remember, there are as many ways to do something as there are people doing them....this is definately true in quilting...you just do what works for you...don't worry about what others say.

I've only heard recently that "you shouldn't be putting your seam vertically on the quilt back!!" (Almost like it was a crime or something) I use a long arm to quilt my quilts, and have never heard of such a "rule" - what reasoning is there behind this?
Thanks in advance.
