The area behind our home is a native prairie with seasonal
wildflowers. As a retired science teacher I am aware of the many spirals in nature’s
wonderful backyard. When the challenge word SPIRAL was given, and I was seeing native
sunflowers, I had my vision and the challenge became how to create this as a 12
x 12.
First, a mini
biology lesson: The
sunflower is actually a composite and is a collection of hundreds of flowers,
packed together next to one another on a platform called a receptacle (the tip
of the stalk where the flower is attached). It is made up of two kinds of
flowers. The disk flowers (tiny
bead-like) in the center will form seeds. The infertile ray flowers are the
‘petals’ (bright yellow). The disk flowers grow in spiral rows around the head
of the receptacle.
Bringing this 12 x
12 image to life: Timeless Treasures is a wonderful photo-treated
fabric, backed with paper, which can be processed through an ink-jet printer. Google
then came to the rescue. After locating the exact sunflower image I wanted, I
made a full color print which would be the background on which to work and then
was ready to select materials and bring this month’s challenge to life.
The center of my ‘composite flower’ is embroidered and would
be where the sunflower buds are just forming.
Out from the center, the buds which will become flowers and then seeds
are beaded. The outside rows are fully
developed flowers and are beaded and embroidered. Finally the ‘petals’ are made
from double sided fabric, fused together with Heat n’ Bond. The ‘petals’ were also shaded with a small touch
of fabric paint.
Just for the fun of
it, a mini math lesson: In the
heads of sunflowers, two series of curves can be observed, one winding one
direction and one winding a different direction and the number of spirals will
not be the same in each direction. The number
of spirals will be 21 & 34, or 34 & 55, or 55 & 89, or 89 &
144. These numbers all belong to the
Fibonacci sequence: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,144, etc. (where the
number is obtained from the sum of the two preceding numbers). This is the most efficient way of filling
space, which maximizes the number of seeds in a given area. Moreover, generally
the petals are formed at the extremity of one of the spirals and therefore
their number corresponds on average to a Fibonacci number. Fibonacci introduced these numbers in the
year 1202 in attempting to model the growth of populations of rabbits.
And finally - an
apology: In my “grand plan”, I
intended to fold the petals that went past the edge of the gallery wrap frame down
and under. When it was time, I just
could not; I really liked the way it looked with the “over-hang.” Therefore, my 12 x 12 is not really a 12 x
12. It’s really 12 and a petal tip x 12 and a petal tip.
