The purpose of this study is to develop a new method for the visual presentation of weaves and woven patterns of dobby fabrics by using the personal computer briefly. The following results were given through adapting this method to the design for patterns of woven fabrics. 1. Complete weaves were given by computerizing the pegging plan and drafting system. 2. The effect of the combined woven patterns were given by computerizing the one complete weaves, the differently coloured warp threads, and the differently coloured weft threads.
