According to Paula: "Use a black thread wrap, mark in a C8 with two
strands of black quilting thread. Tack the intersections OR use
NON-WHITE pins to mark intersections. The pattern uses 8 colors of
Pearl 5 or DMC Craft Thread; for this version I used red for all 12 of
the diamond shapes, turquoise, medium green, yellow and orange for the
8 triangles with each of those colors being used twice, and medium
purple, pink and white for the 6 square with each of those colors used
twice.
1) Find on your marked ball the 12 diamonds, 8 triangles and 6 squares.
2). Place 4 white pins in each diamond so that a=b=c as shown in the
diagram.
3). Use red to place on row of each diamond so that the thread passes
right next to each of the white intersecting pins in each diamond.
4). Place the first row of 8 triangles, 2 of each color on opposite
sides of the ball, again passing by intersecting white pins (8 in each
triangle).
5).Place the first row of 6 squares, 2 of each color in the same
manner. The ball should now look like sample:

Depending on the size of your mari, you will work something like up to
8 rounds so for rounds 2- 8, repeat the same colors in the same order,
one row per color. Leave room between shapes at the end for one row of
black to outline. Add additional intersecting black lines into each
intersecting white pin to trisect the small triangles. Remove the pins
and you are finished.
