I've seen this more than once recently... book guts used as fodder in decor.
As "wow!" as I was initially, as "hmmm, I could do this" when I first spied it, as inspired as I was to rush home & duplicate it... in the end I found out that I just... cannot... do... it.
I cannot bring myself to DESTROY a perfectly good book for the sake of design! Aaarrggghhh! What a dilemma.
Am currently in search of an already destroyed book to make use of. 'Til then, pictures from others with no conscious will have to do.
