I went a little wild on this one! Here is a list of all the uses of Fibonacci numbers:

• 8 sides,
• 21 different teal fabrics
• 13 Fibonacci plaid squares (with units of 1/4 inch: 1/4, 2/4, 3/4, 5/4, 8/4)
  • 8 with orange oriented vertically
  • 5 with teal oriented vertically
• inner border widths are 1/4, 3/4, 1/4 inch
• each of the 8 sides has a different number of "Fibonacci stripe" strips:  1, 1, 2, 3, 5, 8, 13, 21.
• Quilting:
  • each Fibonacci square quilted with 5 concentric squares
  • the teal fabrics between the squares are quilted with 5 lines of stitching
  • the larger solid teal squares are top-stitched in orange with a "Fibonacci plaid" pattern (see the detail pictures)
  • quilting in the border is done 1, 2, and 3 inches apart
• Dimensions of the central area (without the borders) are 44" x 72" = .61, the fibonacci proportion.

Materials: commercial cottons.

Techniques: Machine piecing. machine quilting, top-stitching.
