Homework 1. 2. 3. 4. 5. 6. 7.

Choose a yarn or several yarns and plan a project. Determine the sett (E.P.I.). Is it going to be a tabby or Twill weave? How wide does it need to be in the reed? Allow enough for draw in and shrinkage. Add 10% to finished width. How many total ends do you need to measure? How long a warp will you need to make? How much do you need for weft? Show the math!

Weft Calculation ___________ width of warp X__________ P.P.I. (picks per inch) =__________ Total number of inches per linear inch of weaving X__________ Total length of finished project including 10% take-up =__________ Total number of inches. Divide the total number of inches by 36 to determine the number yards needed to weave your project. Š The Mannings, Thomas E. Knisely, 2003
