+title: preSetDraft
+---
+
+The `preSetDraft` lifecycle hook runs just before a set (of settings) is
+drafted. It will fire once for each set when calling `Pattern.draft()`.
+
+## Signature
+
+```js
+null hook(Pattern pattern)
+```
+
+## Example
+
+```js
+pattern.on('preSetDraft', pattern => {
+  // Mutate the pattern object here
+}
+```
+
+## Notes
+
+The `preSetDraft` hook is rarely used, but it's there if you need it.
