Artist Book-Beginning the folding ideas

I like the idea of a concertina book.  One that as you unfold it you reveal more and more of the same illustration rather than lots of little illustrations.  I did this book as a tester to think about paper, colour, book cover etc.  While i think that the book itself worked, i don't think that it is strong enough to work as an artist book, it's too small - and, the illustration is not strong enough to stand by itself!  The book itself is nice because I've put a hard cover on it and used a ribbon to act as the tie to hold it together so that it stays closed.
