Wish I could help - I am just the photographer, not the designer! Sorry! The designer's name is Shannon Ggem, who is also on Houzz - I am sure she will be able to help!
FYI: You can make your own arrows by purchasing arrow drapery finials, and then making the rod length whatever you like! Then paint to match your decor...
