All of above AND:
I just did a quilt that had 2 1/2" blocks all around the border......they were coming unsewn, so I had to put them on my machine and do a backstitch stitching. I didn't charge extra because I hadn't stressed to do it. If it had had a solid border with 4 seams, it wouldn't have mattered, but all those blocks had been sewn together in strips, then cut to size......and were coming apart.
