The book pages, which you're cutting at 7" square (right?), will FINISH at 6.5" square.
That means that each 4patch will need to be 3.25" FINISHED, UNFINISHED/CUT at 3.75".
I can't read the instructions, but when I did something similar years (and years ago), I sewed the 4patch to the page, right sides together around 3 sides, clipped the corners, and then turned it inside out so the right sides were out.
Then I put a "binding" which encased the raw edges on the 4th side.
Is that what you were planning on doing?
*I do remember I was so mad because on the first couple of pages I sewed the wrong 3 sides - so the "page" was to the left instead of to the right of the spine, which was what i wanted.
Just throwing it out there as something to keep in mind. ;-)
