Test the blend as one engineered yarn. Fiber percentages do not average stretch, abrasion or care behavior in a simple linear way.

## 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

Compare 80/20 and 50/50 blends in equal rib samples. Stretch to the same width and release; select the sample that recovers for a cuff, even if its label seems less promising.

## 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.
