Start from
.
-
Close the two top adjacent tiles (180 degrees valley fold) into a T-shaped planar shape.
-
turn 180 degrees a flap tile such that we now have the T-shape with
two stack of three tiles.
-
lift down 180 degrees a pair of adjacent tiles.
-
turn left 180 degrees two adjacent tiles (with some strain on the strings),
lift 180 degrees a single flap tile and finally turn left 180 degrees a pair of adjacent
tiles to reach the final shape.
