And how exactly would one expand a 108"x108" one-piece backing to 116"x116" without a vertical seam?
Here's my take on that - I usually, if possible, do do horizontal seams because I don't like to have seams showing in the turndown (top 22" of the quilt back).
However, if aesthetically I want/need it, then my long-armers need to deal with it and make it work. ;-)
