Ok... So the first image is the cover it wraps from back to front.
the second image is a stand alone page on the right side when you open the book... just like the last image #20 is a stand alone image at the back of the book.
All the other images are spreads.. the spread from the left page to the right... there will be a fold in the book through the middle of the space. Hope that makes sense.
I did a lot in color at the birth since the light was so beautiful. I can swap more to black and white or images to color... just let me know. When it's good to go I'll order the book.
