Keep the original start and end counts and identify the section that may change. Neckline and sleeve-cap joins must still match their partner edges.

## Before you start

Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.

## Try this example

Adding 4 cm to a straight sleeve section at 15 rows per 10 cm adds six rows. This does not authorize changing the sleeve cap or its attachment count.

## Check your result

- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.
