I can not remember the origamist or the exact origional dimensions
But it can be made with a normal sheet of paper.
First, make a center creace it is only necessary to pinch the edges.
Second, fold the sides to the center and unfold, or I could say creace
Third, turn over the paper, then fold all corners (one corner on the long side to the center of the opposite side) to the opposite center.
Fourth, the paper is still upside-down frol how it origionally was, take the bottom left corner ( I do beleive it has to be the same one every time), and fold it to how it was earlier then kind of squash with the existing folds.
Fifth, repeat on opposite corner, with normal notebook paper there will be "leftovers" that need to be folded.
