This is the front of the paper, the backside is completely white. Prefold over these 4 lines. Then, turn the paper.

Step 6:
Push the edges indicated by the arrows flat from above. All folding lines are prefolded.

Step 5:
Fold the end at the bottom of the arrow upwards by making a valley-fold over the yellow line.

Step 2:
First, make a valley-fold over the 2 lines below, on the right. Then, make a mountain-fold over the 2 lines in the middle. And make a valley-fold over the 2 lines on the top left.

Step 4:
Unfold the folds from step 3.

Step 3:
Make a valley-fold over these 2 lines.

Step 10:
Make a valley-fold over the line on the left and a mountain-fold over the other one. Make the same 2 folds on the backside of the model.

Step 8:
Fold the end above the yellow line downwards by making a valley-fold over this line. Do the same with the end at the backside of the model, see arrow.

Step 9:
Make a valley-fold over the line on the left and a mountain-fold over the line on the right. Make the same folds on the backside of the model.

Step 7:
Repeat step 3 to 6 on the backside of the model.

Step 16:
Make a valley-fold over these 2 lines.

Step 15:
Make a valley-fold over these 2 lines.

Step 12:
Curl the other 3 petals outwards too.

Step 11:
Curl the petal indicated by the arrow outwards.
