LANG
Tip: Compare yarn thickness using m/g (meters per gram). Closer values usually substitute better.

Pattern Yarn

Enter the yarn specified by the pattern, including how many skeins it requires.

Example: 100g/400m × 3 skeins → total 1200m, 300g

Substitute Yarn

Enter the yarn you want to use instead.

Results update automatically as you type.

Lower m/g usually means a thicker/heavier yarn.
