Looks like some post effect or maybe another technique. How to achieve this, any ideas?
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.
