The quiltmaker initially made three rows of three blocks each, D3-F3, D4-F4 and D5-F5. Block E5 was created as the center focal point of the original quilt.
The quilter then added rows to all the sides, and then another set of rows. See the way the black embroidered sashing turns the corners around each of the block sets? And of the sometimes bias cut and sometimes straight cut plaid sashing strips? Also note the Log Cabin "corner" chevrons (Blocks B1, H1, B7 and H7) are very similar in form, with the inside corners facing the center of the quilt. They would have been the corner blocks of the original top.
At a later date, she added rows A1- A7, and A8 - H8. The plaid sashing has again become straight ̶ unlike the bias cut of the original top, and there are several silk checks and plaids which do not appear in the original center.
Later still, she added row A9-H9. Look at the way the black embroidered sashing is placed, and the way the bias cut border is constructed.”
