```js
|
|
|
|
|
float utils.stretchToScale(float stretch)
|
|

```

The way people measure stretch intuitively is different from the way we handle stretch in code.
|
|
|
|
|
|
|
|
|
|
When people say *25% stretch* they mean that 10cm fabric gets stretched to 12.5cm fabric.
|
|
|
|
|
In code and on our patterns, that means we need to scale things by 80%.
|
|
|
|
|
|
|
|
|
|
This method does that by returning:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
1 / (1 + parseFloat(stretch));
|
|
|
|
|
```
|
