|Material||:||Cherry & Walnut|
|Pieces||:||18, plus the tray|
This puzzle is based on the Arabic interlace pattern that includes four different basic elements of straight and curved lines. The eighteen pieces are all of the possible ways of connecting three basic elements within the pattern. When together, the pieces lock together and hold one another in place while leaving open spaces that reveal a beautiful contrast between the wood of the pieces and the wood of the tray. Note that some pieces are fixed in the tray, such as those at the bottom in the photograph.
