Mark a Japanese Temari with 32 Centers

When you are ready to step beyond the combination 10-division, wrap a larger ball and keep dividing. From the C10, you can add more guidelines to end up with 32 centers equally spaced about the ball. Before you begin the 32, make sure the C10 is marked as accurately as you can, and all of the 10-spoke and 6-spoke intersections are tacked. Leave guidepins in place at all these intersections.
All of the marking is usually done with the same type of thread. The drawings below show different colors to make the instructions more clear to you. After you get the pins in place, there are several different methods to stitch the guidelines to end up with 32 centers on the ball. Choose a stitching path that you like and can remember. The diagrams show half the ball or 21 centers.
Have a look at the geometry behind the 32 and the 42 multi-centered division.
Here are some photos of the 32 center marking that may help!
Pin placement
Measure the distance beween 2 of your original C10 centers (centers of 10-part pentagons). Divide that distance by 3. Place pins at the 1/3 and 2/3 points. Go ahead and measure and then place pins for the rest of the ball.
Hint: cut a paper strip the length of the distance between 2 of the C10 centers. This is your "magic number" you used when you marked the C10. Fold the paper strip in thirds and notch the crease marks. Use this paper strip to place pins at the 1/3 and 2/3 points.
Method 1
1. Stitch a star inside a pentagon as shown. After you have stitched the 5 points of the star, go ahead and tack the intersections at the pins and remove them.
2. Stitch a star in another pentagon. Tack as before.
3. Stitch stars in the remaining pentagons and tack as before. Tack intersections in centers of 6-part triangles.
Method 2
1. Stitch a pentagon connecting 5 pins around a center.
2. Stitch a larger pentagon around the same center.
3. Turn the ball so another one of the centers of a 10-part pentagon is facing you. Repeat step 3 and 4. Continue this same pattern all over the ball until each of the twelve 10-part pentagons is done. Then the 32 multi-centered division is done.
