set "Your classic photobook" includes 5 double templates + bonus - more 3 variants of templates ( 24x12 inches, 7200x3600 pix).
So each page in your book will be harmonious and you will not have to think about how to pick a pair of your single layouts.
See samples of using double-templates in further images.
All templates include styles for each layer (not only sketch) and other properties.
Just add your photos!
All templates are in 3 versions: PSD, PNG & TIF.
Use the format which is comfortable for you.
