As referenced in my Zatchbell Spell book Tutorial series, here are the PDFs of the spell book pages:
Each of the page sets above (A, B, C, D) are made of each of the 4 pages, in different orders with different colors. Pages 1, 2, 3, and 4 are sized for 8.5″x11″.
For example, to make ‘Page C’, you might take page 2, 4, 3, and 1 in that order with particular colors. Then for ‘Page D’, you might take page 4, 3, 2, 1 in that order with different colors to make the spell pages look more unique.
