And then take this point, and fold it down
to this line. Same thing for all four sections – we’re going to do that for all four sections.
Open it, and finally the last section. Fold the raw edges in, fold this point down. Now,
we have done all the folding, we are going to completely unfold what we’ve just done,
back to a sheet of paper, back to just one layer back. And now, what we are going to
do, is invert our folds so that now the green side is on the outside, originally it was
on the inside. And following the creases we made, take this section, this square section,
and follow the creases, and fold these edges back in, and fold that point down.
