About
Me
When I
was 8 years old, I learned to crochet - a potholder out of
yarn first, then a doily out of thread. I was mesmerized by
the idea of creating something beautiful. And thus began my
creative journey. Since then I have tried many crafts. Some
were fads whose popularity (and availability of supplies)
came and went. Many are traditional crafts and variations
on them. All are self-taught. Among my favorites: crochet;
counted cross-stitch; Christmas ornaments and decorations;
and quilling, the most artistically satisfying of them all.

June Treasuries
Etsy treasuries are collections of 12-16 items based on a theme
or similarity. They are created by Etsy members (called curators)
featuring their favorite selections from other members' shops. In
June items from my shop were included in a few treasuries (click
on a photo to see the treasury):

Brainy Fun
While
researching the chambered nautilus for last month's team challenge,
I came across something that intrigued me. Although all my creative
work is, well, creative (right brain), I also enjoy intellectual
endeavors - I love things that tickle my (left hemisphere) brain
cells. And so I share with you the Fibonacci Nautilus.
In 1202,
Fibonacci of Pisa introduced Arabic numerals to Europe.
He also developed a sequence of numbers to solve a problem
involving the growth of a population of rabbits based on idealized
assumptions. This sequence later became known as Fibonacci
numbers - each number in the sequence is the sum of the previous
two numbers. The following sequence begins with 0 and 1:
0,
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610,
987...
|
|
0
+ 1 = 1
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
and so on... |
|
|
Consecutive
"Fibonacci numbers" divided by each other result in a ratio
of about 1 : 0.62 or 1.62 : 1, depending on whether
the higher or lower number is the divisor. Higher up in the
sequence, this division approaches what he called the golden
ratio (approximately 1 : 1.618 or 0.618 : 1) |
|
233
/ 377 = 0.61803715
377 / 610 = 0.61803278
610 / 987 = 0.61803444
and so on... |
|
|
This ratio arises
in nature in several places. It can be used, along with a logarithmic
spiral to construct a shell of a chambered nautilus out of right
triangles.
|
Reminder:
A right triangle is a triangle in which one of the three angles
measures 90-degrees. The side opposite the right angle is called
the hypotenuse. The relation between the sides and angles of
a right triangle is the basis for trigonometry. |
Starting with
the largest triangle, glue them to a background in a counterclockwise
direction by placing each successively smaller triangle's hypotenuse
next to the previous triangle's longer side. The 11 triangles make
nearly one complete revolution. The short sides form the outside
of the shape, which makes the spiral.

Etsy Team Challenge
As
described last month (see Archives), my Etsy team had a challenge,
just for fun. This was my entry and is now available in my Etsy
Shop (click
here). Check out all 4 entries on the PaperTwirlies
blog.
I
like this design so much that I made one in more natural/neutral
colors and mounted it on deep turquoise cardstock. This one is also
available in my Etsy shop (click
here).
