Please note that the previous outer circle pattern is not shown at first for clarity of round two.

The inner circle is a relative of the "v" form of practice 3 and practice 7. Studying the structure and spacing of each line makes it possible to draw out the arrangment by just "counting" the points.

Each beginning line ( the top line) from the center circle has 1 empty space between it and the next beginning line. Each ending line(the line below) on the inner (2nd) circle has 5 empty spaces between each double "V" group, and 1 empty space in the middle of the "w" at the bottom. Check it out!(Middle drawing).

Strictly by numbers (top drawing) it's point 71 outer circle to points 69 and 1 on the center circle, then point 1 on the inner circle to points 71 and 3 on the center circle, completing the first "w" group. Now, skip one space on the center circle and 5 spaces on the inner circle and construct the 2nd group: point 7 (bottom) to 5 and 9 (top) and point 9 (bottom) to points 7 and 11 (top). Keep going all around.Go ahead--it's very easy.

AT LAST, THE CENTER

The third area of design (other areas removed) is the center section which will house 2 equilateral triangles and invite individual pattern options.

The first connections all on the center ring, are from point 24 to point 48, 48 to 72 and 72 back to 24. The second triangle is drawn behind this one, from points 12 to 36, 36 to 60, and 60 back to 12. Easy as pie!
