How do you calculate weaving?

To calculate the amount of weft, you need to know warp width, the number of picks per inch, and the length of the weaving. I usually add ten percent to that number for weft take-up. (So for an 8″ wide warp woven at 20 picks per inch for 65″: 8″ x 20 x 65″ = 10,400″ divided by 36″/yd = 288 yd plus 10% = 317 yd.

How is warp shrinkage calculated?

To determine the take-up and shrinkage in width, divide the finished width by the width in the reed and you will get . 912, which is the total amount of width you would get from a 23” wide warp in the project’s yarn type. Resulting in about about 9% take-up.

How much yarn do you need for weaving?

I’d calculate 15% for take-up and shrinkage (that might be a little high, but it’s better to figure too much than too little). So you’d need to weave 65″ divided by . 85 or about 76″ measured on the loom. I’d therefore put on a 3-yd warp (108″), which would leave 32″ for loom waste; the loom waste would include fringe.
