This "open heart" book folding pattern uses 552 pages if you fold it the normal way (strictly according to the pattern). Print this out on a regular 8.5 x 11 sheet of paper in landscape orientation. Be sure to use a hard-cover book for your project!
You can also do a variation on this pattern where you fold every fourth page straight up and down halfway back to the spine. This variation uses 736 numbered pages. The second image shown for this item is a closed heart with the in-between pages folded halfway back, so you get an idea of how this variation would look.
The special instructions are included in a DOC file.
If you haven't used my patterns before, be sure to practice with the test "e" pattern to understand how to fold pattern with multiple levels. If you don't understand how to do this, you will run out of pages before finishing your pattern.
This purchase comes with a FREE HEART pattern for 320 pages.
