QuiltE - great feedback. I hadn't considered how a center seam might look on the bed. This will be a queen size so doing a WOF in the middle and 1/2 on each side might work. How the seams look is one of my concerns. I like it to look purposeful, not oops.
Your feedback is one of the reasons I came to this group. We all have different views and perspectives and often others think of things I didn't.
