Weaving Calculation

The document provides instructions for calculating the warp and weft requirements for a balanced fabric. It includes a table to enter the lengths of fabric pieces, fringe, and hems. It also has fields to specify shrinkage, takeup, warp width, ends per inch (EPI), total warp threads needed, and the total yardage of warp and weft yarn required. The final step is to draw a picture of the project. All of these inputs are needed to determine the correct amount of yarn to weave a balanced piece of fabric to the specified dimensions.

Shrinkage is typically 10 to 15%, more for wool, less for cotton. Takeup is also typically 10 to 15% more for larger threads, less
