setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: Pattern.render()
+---
+
+The `Pattern.render()` method will render the pattern to SVG and return
+that SVG as a string. It should only be called after calling
+[Pattern.draft()](/reference/api/pattern/draft/) first.
+
+## Pattern.render() signature
+
+```js
+string pattern.render()
+```
+
+## Pattern.render() example
+
+```js
+import { Aaron } from "@freesewing/aaron"
+
+// Load some public test measurements from the FreeSewing backend
+const measurements = (
+  await (
+    await fetch("https://backend3.freesewing.org/curated-sets/1.json")
+  ).json()
+).measurements
+
+const pattern = new Aaron({ measurements })
+
+const svg = pattern.draft().render()
+```
