Bid Majnun( weeping willow) design is in the invaluable position because of being one of the most famous patterns among Persian rugs as well as their local varieties. Although it seems that there is not a particular region for the creation of this design , old samples have been observed in the north-west areas of Iran especially in Bidjar(Bijar). Such evidence may imply that Bidjar has been the source of this pattern. Using broken and semi-curvilinear lines and average weave cause to consider such rugs as local ones. Basic elements of these rugs are motifs such as weeping willow, cedar, poplar and fruit trees. These features in a balanced combination have made a common pattern which has been used in Chaharmahal & Bakhtiari province, the north-west areas of Iran and even in the other countries. This study attempts to reveal different varieties and the construction of the pattern of Bid Majnun through analysis of 20 samples from the main local areas in Iran. This research has been conducted by using descriptive statistics based on the comparison of the data. Data collection procedure has been accomplished by using field and library-based studies. As was briefly mentioned before, the results show that Bid Majnun design has a unique structure with a special design in different regions. Meanwhile, a little change in the construction of motifs has caused some variation in the pattern of Bid Majnun.
