Be Confident with Yarn Substitutions

Match the Yarn Weight

When your pattern calls for sport-weight yarn? Use another sport weight to keep sizing close—but always double-check. Not all sport weights are equal. One sport yarn may be thicker or stretchier than another. You also want to take into consideration yarn texture and fiber.


Always Knit a Gauge Swatch

  • This step is non-negotiable if you want your sweater to fit.
  • Use the recommended needles
  • Knit at least a 4"x4" swatch
  • Block it like you’ll block the finished sweater
  • Count your stitches and rows per inch
  • Adjust needle size to match the pattern’s gauge

Compare Fiber Content - Matching fiber = better fit, shape, and durability.

Substitute with a yarn that behaves like the original:

  • Wool = elastic and warm
  • Cotton = breathable, less stretchy
  • Alpaca = soft with drape

Calculate Total Yardage

Don’t match by skein—match by total yards/meters.


Consider Color & Texture

  • Solids show off stitch patterns
  • Variegated may pool or hide texture
  • Smooth vs. fuzzy yarns give different finishes

Have fun! When you substitute yarns you're able to customize the sweater to waht you want and that's what knitting a sweater should be about.  Give us a call if you need help, Andrea
