Fold in the edges along the dotted lines shown. : Now you have four little flattened squares. : Take one of the little flaps you folded in the last step, and flatten it into a square, like the one on the top-right of this photo. : Now there are some loose flaps at the top and the bottom. Fold the top flap to the right, along this dotted line.
: On the left side of the note, there are two big triangular flaps. : Fold the little corner tabs, along the lines shown. (It will fold into this shape naturally anyway, because of the creases you made in the previous steps.) Then fold in half, right to left. : Turn the bill over again, and fold it into this shape. Each fold goes through the centre of a 'cross' from the previous step. : Turn the bill over, then fold and unfold along these dotted lines.
Folds are at 45 degrees, so they bring the side of the paper into line with the top or bottom. : Fold and unfold along the dotted lines shown here. Anyway, don't be alarmed by the number of steps. No, wait, it wasn't a wise person, I saw it written on a fridge magnet. A wise person once told me, 'bit by bit, one by one, suddenly, job is done!'.
