I am working on an interesting Norman Gothic building project and drafting some stone masonry elements as and when needed , here are two more tracery patterns.
Feel free to use and edit/modify, re-scale etc. as you wish  
 
* When I get time I will add the drawing procedures to the Tips and Tutorials section in the forum.
