5/30/01 Note - These pages will help you work through getting proper measuring and dividing for a C10 with minimal "math" - you only need the diameter or circumference of your mari. For those with less math anxiety, there is an alternate method to determine the distance between the marker pins (the pins you place using the distance you find below) - when done properly, these pins ( regardless of the method used to mark) are all equidistant from their neighbors, and their pole. To determine this distance, you can multiply the circumference of the mari by the constant 0.177 - that will give you the same distance that you are working toward described in the next paragraph. The kicker here though is that you need to be sure that you are accurately measuring the circumference, around the full middle of the mari. Once this product is calculated, cut a strip to that length or similar means to measure the pin placement on the vertical divides.  (with thanks to Kiyoko and Karen Mc.P)

        Those in the US tend to refer to Temari sizes by inches in diameter, and most other countries by cm in circumference actually much better). Needless to say this can cause some confusion in general conversation, let along when one is trying to technically discuss working out a pattern. For working a C10 division using the paper strip method, this chart gives you all the numbers you need after you measure the circumference. It converts the measurement to cm first from inches, then uses the cm measurement to list the needed 1/5th divisions needed to space the 1/10ths to vertically mark the ball (divide the strip into fifths and then the folded strip in half). It also shows the 1/100th add on that you must use with the 1/3 of the half-circumference to position the ten pairs of pins. This is not a tutorial in working a C10 division - see basic Temari books or the C10 Tutorial on this site.

        The chart will not display at its best on your monitor - it is designed to be printed, and will fit on one page. Be sure to extend the margins on your page set up in your browser, and turn off the date/time and page number indicators. It covers mari sizes from 2 inches (15cm) to 5 inches (40cm). It is much easier to get accurate divisions on a C10 ball if one uses metric measurements and for many in the US using metrics is still difficult. Once the initial measurement is determined either in inches or cm, then simply locate that mari size, and the numbers you need to work the division are given to you. The formulas and conversions used to determine this information from a circumference measurement are noted in the center column. While the chart will hopefully eliminate the "math anxiety" part of doing pentagon divisions, I do urge you to become familiar with working the numbers Even for those of us comfortable with it, this will makes things a bit easier for all. I have worked and rechecked the numbers, but if you should find an error please let me know. I will in time work it all into an html table rather than one scanned table, but it will take some time given the number of entries.
