Keep one complete length budget for each yarn. For 400 m of working length plus 10% reserve, both A and B need 440 m, then their package quantities round separately.

## Work through the example

1. Choose the pair and make a finished sample with both strands. Record handling, stitch density, drape and a care method suitable for the pair.
2. Establish the 400 m base working length from a representative estimate or a pattern for the same fabric. Do not take a single-yarn pattern quantity as automatic proof.
3. Enter one strand of A at 100 m/50 g and one of B at 200 m/25 g. The result is five A balls and three B balls.
4. Plan how to manage joins and keep both strands feeding consistently. Label A and B separately so a partial ball cannot be mistaken for the other.
5. Print the two quantities and attach the sample notes. Recheck the budget if one strand is removed in any section.

## Check before committing

The calculation assumes both strands run together for the entire entered length. It does not predict the resulting yarn category or a suitable needle or hook.

Inputs and sample measurements recorded; chosen result checked; material/color references recorded; reserve included once; construction and finishing checks completed.

## Method and sources

These are original planning examples using the linked tools’ methods. Replace measured inputs with your own samples; a calculator cannot validate the construction. Keep the resulting measurements, choices and remaining checks with the project.

## [Held-together yarn planner](https://threadcabin.com/tools/held-together-yarn-planner)

Plan label-based quantities for one or two yarns held together. Enter the working length needed by each strand, not an already combined total.

Enter the working length needed by one strand, not the combined length of every strand. Select how many strands of A and B run throughout.  Each strand consumes the full working length; B can be zero. This estimates separate packages, not the combined yarn weight category or gauge.

Each working strand needs the entered length plus allowance. For each yarn, multiply that length by its strand count, divide by label length, and round up to whole balls. Total purchased mass is the sum of each ball count × label mass. It assumes all strands run together throughout; estimate separate sections separately.

- Required length per working strand: 400 m
- Extra allowance: 10 %
- Length per ball: 100 m
- Weight per ball: 50 g
- Strands held together: 1
- Length per ball: 200 m
- Weight per ball: 25 g
- Strands held together: 1
