Monitor sub folders

I am totally new to Hazel and can someone please help me with the below.
I am looking to move a folder containing a specific extension to a separate location.
For example, when downloading font files a subfolder is automatically created in Downloads. So, can Hazel recognise the .otf or .ttf extensions inside this subfolder in the Downloads folder and then move that specific sub folder to a different location, maybe a folder titled Fonts.

You can have a rule match a folder based on its contents. Look up "nested conditions" in the help.
