Za njenu izradu je potrebno : drvena ploča cca 20x20 cm, čavlići, vuna ili deblji konac. Vuna se zaveže za jedan čavlić, i odredi se broj s kojim će se namatati vuna/konac. Ako je to broj 2, za svaki drugi čavlić će se namatati, 5- svaki peti, 7 - svaki sedmi itd. Broj krugova nije određen.
To create a mathematical board you need: a wooden board approximately 20x20 cm, pins, wool or thicker thread. Wool tie a tack, and determine the number from which to coil the wool / yarn. If this is the number 2, for every other tack would roll up, 5 - one in five, seven - one out of seven laps etc. The number of rounds is not specified.
