+Reusable freehand drawing and erasing plugins for Plait boards.
+
+```ts
+import { createFreehandPlugin } from '@plait-board/freehand';
+import { withOptions } from '@plait/core';
+import { withDraw } from '@plait/draw';
+
+const withFreehand = createFreehandPlugin({
+  getDrawOptions: () => ({ strokeWidth: 2 }),
+  isInteractionBlocked: (board) => isPinching(board),
+  createEraseTrail: () => new MyEraseTrail(),
+});
+
+const plugins = [withOptions, withDraw, withFreehand];
+```
+
+Application-specific toolbars, persisted presets, gesture policy, and eraser-trail presentation can be supplied through `createFreehandPlugin` options.
+
+## Development
+
+```sh
+npx nx test freehand
