Construction
The first girih patterns were made by copying a pattern template along a regular grid; the pattern was drawn with compass and straightedge. Today, artisans using traditional techniques typically use a pair of dividers to leave an incision mark on a paper sheet that was been left in the sun to become brittle. Straight lines are drawn with a pencil and an unmarked straightedge. Girih patterns made this way are like a two-dimensional crystal, tiling the plane with a unit cell. Because the tiling was done by translation or rotation operations, the unit cells had 2-, 3-, 4- or 6-fold rotational symmetry.
