Assembling large title plans
Fold the plan
Horizontal folds
At the horizontal taped join, fold the bottom row up one, printed sides together.
Fold the next row up in the same way, and so on until you're left with one long strip.
Vertical folds
Fold the left-most page on top of the next, along the vertical taped join.
Continue this way, from left to right, until you've folded all onto the header page.
Your assembled plan is complete.
