for making it we need
card (preferably thick)
on the back side of front view/side draw 2 small circles (approx 4cm in diameter)
draw an inclined vertical line to divide the circle in 2 semicircles
do the same with another circle
now on that diameter including the end points draw 13 points (refer photo)
and on both semicircles circumference draw 24-24 points (excluding end points of diameter)
please refer photos
do the same with 2ns circle
use needle and punch every point using needle
tie a knot at one end
pass another end through needle
then take out needle from 2' and pass through point 2
then take needle from 3 and pass through point 3'
then take needle through 4' and pass through 4
continue this process
after taking needle through 13 and passing through 13'.. take needle out from 14' and pass through 1'
then take needle through 2' and pass through 15'
then through 16' and pass it from 3'
continue this procedure until thread reaches to point 1 back again
then take needle through 15' and pass through 24'
then tie knot at the back side (make proper knot or else seal knot using tape)
