Many studies have been carried out regarding the appearance defects of stitches in decorative seams; But so far, the assessment of stitch deviation in decorative seams has not been investigated. Among the applications of decorative seams, it can be used in clothing items such as outerwear, including coats, jackets, etc. In addition, it is also used in the automobile industry, such as covering car seats, in the industry of making balloons and traveling tents. Considering the negative effects of stitch deviation on the sewing appearance, reducing the amount of this phenomenon in the textile output improves the appearance characteristics of manufactured textiles, which requires the eva‎luation and analysis of stitch angles with the horizon under different conditions. Therefore, in this research, the deviation of the stitch in the sewing area and the consumption rate of the sewing thread in the samples prepared from two layers with the same material (denim or leather) and the effect of sewing parameters such as the type of sewing thread (cotton, polyester or 100% poly Ester), sewing thread tension, presser base pressure, sewing speed and needle score were eva‎luated in the degree of stitch deviation. Then the scanned images were checked by DigiMizer software and the amount of stitch deviation, the number of stitches in each sample and the length of the thread on the work were measured and finally modeling was done with the help of Solidorex software. The results of analysis of variance showed that the parameters of sewing thread type and needle score had a significant effect on reducing or increasing stitch deviation compared to other parameters. Also, the results of variance analysis showed that the parameters of fabric type, sewing thread type, needle score and sewing thread tension had a significant effect on reducing or increasing the rate of sewing thread consumption compared to other parameters.
