Understand yarn-weight categories
A yarn-weight category describes a broad thickness range, not package mass. Use it to shortlist candidates, then compare finished gauge and fabric.

A yarn-weight category describes a broad thickness range, not package mass. Use it to shortlist candidates, then compare finished gauge and fabric.
Before you start
Keep the exact labels and make two comparable samples. Change one material property at a time and use the intended finishing method on both.
Try this example
Two 50 g balls can carry 100 m and 200 m. Equal package mass does not make them interchangeable; sample the proposed replacement at the project gauge.
Check your result
- Compare the dry samples for recovery, surface, drape and the property needed for the project. Record observations separately from label claims.
- A fiber name or category cannot predict every finished fabric. Construction, treatment, gauge and use all affect the result.
