Grist Calculator

Grist is such a useful measurement for hand spinners. Learn more by watching this video.

How to use the Yarn Grist Calculator

You will need:

• Weight of skein or sample (grams or ounces)
AND
• Total length of skein or sample (metres or yards) OR the circumference of your skein (one wrap of your niddy noddy/skein winder (cm or inches)) AND the number of times you wrapped the niddy noddy.

Measuring the length of one loop in a skein of yarn to calculate grist.
