Running out of yarn mid-project is worse than buying one spare skein you never use.
Turn the yarn your project needs and a spare margin into the number of skeins to buy.
Knitters and crocheters who buy yarn by weight and want a sensible spare.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Use the pattern's yardage or weight. If you have a swatch, scale from its real use.
Note the grams per skein on the label. Labels can differ from the weight you expect.
Add a spare percentage so a short skein does not stop the project.
Divide the total by the grams per skein and round up to a whole skein.
Buy every skein from the same dye lot when you can. Keep the spare for repairs.
A project needs 400 grams, skeins hold 100 grams, and you add 10 percent spare. You need 440 grams, so buy 5 skeins.
Use your own source and details. The example is not a record about a real person or organization.
