Turkish Map Fold with a Square Sheet of Paper

I’ve used this folding technique for my book Summer (shown below) as well as a model I made, shown in this blog post. David Rosen taught me this fold and he had instructions on his website, but they (and it) have unfortunately disappeared. See this page for instructions for a non-square piece of paper, as well as several variations and ways to use the fold in a book.

Turkish Map Fold with a Square Sheet of Paper

mapfold2.jpg Fold a square sheet of paper in half, along the grain.
mapfold3.jpg Open it and fold the sheet along one diagonal.
mapfold4.jpg Open it and fold along the other diagonal.
mapfold5.jpg Open the sheet and push the gray areas of the sheet together along the horizontal fold (you are reversing this fold).
mapfold6.jpg The sheet should look like this now.
mapfold7.jpg Fold the edges (wings) of one side to the middle.
mapfold8.jpg Open the wings and push them toward the center along the diagonal fold, reversing the folds as you push in (this is the trickiest part of the fold).
mapfold9.jpg Your sheet should look like this. Turn it over and repeat the last 2 steps.
mapfold10.jpg This is what the folded sheet should look like when you’re all done.
