Its a book inside a book. I started off making a mini book. here is the link to a website that explains it really well.
I did this mini book in a class I took for free (free is a very good price.) In the class the instructor had the most awesome clip art so the entire mini book is clip art and rub on lettering.
I painted the two page spread with Golden's heavy body acrylic paint in payne's grey. I just did it haphazardly to give it a lot of texture. The lettering is from a text sheet of paper and using my sizzlit machine. I am not sure of the font. I adhered the mini book in the spine of the book.
Now I have a page that has pages to turn on it.
This mini book can actual be a big book too just use larger paper with the same dimensions. Lynne Perrella does this times and it is awesome.
