I've been staring at the individual photos of the blocks and the author's interpretations of the blocks -
L-11, for example, page 111
I know the author had the advantage of seeing the quilt up and personal.
But from the photo, it looks like Jane's seam lines are different than the drawn ones.
L-10, on page 111 - took me awhile to realize that the photo is rotated 1/4 turn from the drawing - no wonder it didn't make sense at first.
