How much weft yarn do I need?

  1. Take the width of your project in inches and multiply by 125%
  2. Multiply the result by the number of rows per inch that you weave.  This will give you the number of inches of yarn per inch of weaving.
  3. Multiply the result by the number of inches in your weaving.  This is the total number of inches of yarn you will need.
  4. Divide by 36 to get the number of yards you’ll need.
  5. Allocate the result based on the relative amount of each color you will use.
  6. You can’t have too much yarn, so don’t worry if you go over.

Example: 24″x36″ rug

  1. 24″x125%=30″ per row
  2. 30″per rowx40 rows per inch (or number of rows you weave per inch)=1200 inches per inch of weaving
  3. 1200″ x 36″ inches of weaving = 43200″ total for project
  4. 43200″ / 36″=  1200 yards of yarn needed or about six skeins of #1

    Is the three ply warp yarn made from churro wool?
