Combine comparable usable lengths after identifying material, color and batch.

## 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.

## How to do it

1. **Measure remaining material from a label** — For one uniform yarn, estimate length from net remaining mass and the original length-to-mass ratio. Remove packaging and keep uncertainty from scale resolution visible.
2. **Combine compatible leftovers** — Sort leftovers by usable length, behavior and care needs before color. Keep separate groups when the yarns cannot substitute within one area.
3. **Combine component quantities without mixing colors** — Two parts using 120 m and 80 m of color A total 200 m before reserve. Color B uses 60 m separately. At 100 m per ball and 10% reserve, buy three A balls and one B ball.

## Try this example

Three matching leftovers weigh 20, 35 and 15 g. At 200 m per 100 g they contain about 140 m; subtract unusable ends and keep a reserve before choosing the project.

## 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.
