Lensbaby photo book

I looked outside the other night, just before the sun was setting and noticed how beautiful the trees and buildings looked. I took out my camera and lensbaby and took some photos of it there and then. The book is half finished, I have no idea wether a soft cover would suite or a hard cover, or even something else? The photos themselves were purely black and white, but my printer decided purple, black and white would be a nicer. I have to agree, my printer was right.
