Abstract
NAWA is strung by twisted bundles of straw. The process of crafting NAWA is not well known generally. For this reason, the process involves a special skill at crafting NAWA with hands. The purpose of this study was to investigate the relationship between skill level and the physical characteristics of NAWA. Tensile test was carried out, and cross sectional photographs were obtained. Also, three-dimensional upper body kinematics data was collected. The resulting data show that the movement of arm related with strength and structure of NAWA.
