Yarn Substitute Finder & Alternative Yarn Matcher

When a pattern calls for a discontinued yarn, an expensive imported wool, or a fiber you are allergic to, finding an accurate substitute is essential. Our Yarn Substitute Finder matches yarn weight classes, fiber composition, and gauge requirements.

Key Criteria for Yarn Substitution

  1. Yarn Weight Category & WPI: Both original and substitute yarns must belong to the same CYC weight class (e.g., #4 Worsted).
  2. Fiber Drape & Memory: Animal fibers (merino wool, alpaca) have natural bounce and stretch; plant fibers (cotton, linen, bamboo) are heavy and inelastic.
  3. Meters-per-100g Ratio: Compare yardage density. If Yarn A has 200m per 100g and Yarn B has 200m per 100g, they have virtually identical strand thickness.
  4. Gauge Swatch Verification: Always work a 4x4 inch swatch using our Gauge Swatch Calculator.
