Look at this GFG unit and the use of the check and plaid with the small floral print at the center of the flower. Some of the units were consistent in the use of matching fabrics in each successive ring of hexagons. You can see several more units that "match" in the photo above.
But there are just as many units that are random and more haphazard incorporated into the quilt top. I count 14 fabrics used in the hexagons at right. And there's that same pink floral at the center. I like the quiltmaker's "no rhyme or reason" approach to combining the pieces for her quilt. It adds to the carefree, make-do feel. Plus the choice of red for the "path" between units is unique. I'm not sure I've seen it used, or at least if I have, it's been infrequent.
Also inside the box were stacks and stacks of pieced blocks, many with a complex pattern like the ones below. The little LeMoyne Star blocks at the very bottom of the photo are only 5" or 6" square.
