This document provides instructions for using a thread consumption tool. It outlines 7 steps to determine thread usage for a garment: 1) join shoulders, 2) set collarette, 3) tape shoulder and neck, 4) hem sleeves, 5) close sleeves, 6) set sleeves, and 7) hem bottom. For each step, the user inputs stitch type, rows, stitches per inch, and seam length. Total consumption can then be calculated for a single garment or lot. Cost, planning, and unused thread amounts can also be determined.
