Build a repeating assembly unit whose joining edges actually match.

## 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. **Arrange mixed-size motifs** — Use finished joining dimensions to define a common module. Two small motifs match one large edge only after their internal join is included.
2. **Measure a motif after blocking and joining** — Use the distance between corresponding points of joined motifs. An 11.5 cm loose square with a join adding 0.5 cm per repeat has a 12 cm pitch in this example.
3. **Plan and join crochet motifs into a finished project** — Measure the joined repeat, plan rows and columns, arrange colour, and test a seam before assembling many motifs.
4. **Budget crochet yarn by color** — Measure each color’s consumption in a representative motif or stripe, including carried yarn and ends. Round package quantities separately for each color.

## Try this example

Trial one large square beside two small squares including their shared join. If the small pair spans 21 cm, a 20 cm large square is not an interchangeable unit; revise the sample before counting blanket modules.

## 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.
