Answer
You could use the Wrinkle tool. It’s located in the Tool bar as shown below. Double click the Tool icon to change settings as required. These are the settings I chose.
Then use the tool as you would normally use the Brush tool, over the edges of a rectangle or shape, until it’s rough enough.
The other answer given covers the addition of stippling/shading. So I won’t repeat that. However just to say that using the Wrinkle tool is a vector effect, rather than a raster filter.
