Take a square sheet of paper and fold it diagonally.
Then fold this part like this.
This part, which opens, should be at the bottom.
Fold this end over here, like this.
Repeat for the other side.
Fold this part down, like this, leaving a little space here.
Do exactly the same thing on the other side.
Everything must be symmetrical.
Taking only one leaf, fold this point below the horizontal center line while following along the vertical center line, like this.
Repeat this a second time, but fold this part slightly above, leaving a little space between the two.
Once you have this shape, flip the origami over, and fold this part close to the center line.
Leave a little space and try to keep the folds as parallel as possible.
Repeat this process for the other side.
Your cicada is done.
