I was hoping to get a close-up view when I visited the quilt this past weekend. However, this year the quilt was displayed in a different area, with less light, and you had to stand further back. So I really couldn't tell if there were seams or not, even in person.
Jane's Block

I've stared at all the photos I have, and the poster, and the quilt, and it always looks like one of the corners is pieced (the bottom left corner) to make a complete circle, the way my pattern is. But a couple of the corners definitely look like they're not pieced. So I created a second pattern without pieced corners.
Pattern Changes

If I make this block again, I'm undecided as to which pattern I'll use.
