Here are some photos from a restored section of  the faux bois arbors in the Rose Garden of 
The Huntington Library, Art Museum, and Botanical Gardens  

This fellow, a Red Tailed Hawk, landed right next to me.  
​I just love this place!

My color blending of old and new faux bois looks good even when the material is wet.
 
I achieve this by mixing a fine slurry of a grout color that matches the old material.  In the final coloring steps, it is used as a dry brush highlight.  In this way, color tones can be worked back and forth.

I use a disposable pastry bag to put pressure behind my mud.
​This pushes it into into voids and makes some interesting textures.
