In (his study. sewing thread consllmption, one of the major cost expenses, is examined. The purpose of the study is to examine the effects of fabric thickness on sewing thread consumplion. The accurate ly determin ing of sewing thread consumption re lated to fabri c thickness and applying i( (0 the production. provides the control and reducti on of thread costs. In addition, stock costs also decrease. In this study 10 diffe rent fabrics in different thickness are selected as spec imens. 11 00 samples in the dimensions of 3 x 100 em arc prepared. Each sample is sewn by llsing lock-sti tch, 2 thread, 3 thread and 4 thread chain stitches. The da ta arc evaluated in SPSS software. According to the results or variance analysis. (he e lrCCl of fabric thickness on sewing thread consumption is statistically signiticant.
