I made a book for Stine for her 30' birthday. "only" 80 pages - size 12X12" - best quality paper. That one cost me about 180$ to get..... Which I think is up there....
Of course I can chose lesser quality paper to lower that price.
The biggest book on Blurb is this one (12x12 or 13x11" landscape format.)
I'll see what I can do.
Thanks for your comment.
