1. Slice off the top of the soap.
2. Draw a 2 cm (7/8") diameter circle with a toothpick.
3. Holding your carving knife at a right angle to the soap, deeply cut the circle.
4. Thinly cut off the soap inside the circle.
5. Trim the side of the center and smooth the soap around the center.
6. Lower the top of the center a bit.
7. Insert the kinfe tip diagonally into the center, then make an inverted cone shaped indent.
8. Cut some slits in the edge of the center to create the stamens.
9. Draw a 3.3 cm (1-3/8") diameter circle, then divide the circle into 6 equal parts.
10. Make two straight cuts from the center.
11. Cut the soap between two cuts along the circle.
12. Cut the soap again to remove the soap as below.
13. Repeat steps 8-10 in order to carve a long petal.
14. Repeat steps 8-11 to carve other five parts.
15. Cut each part into a pointed petal shape.
16. Trim the outside of the petals. Six petals of the first layer are done.
17. Draw a 5 cm (2") diameter circle, then divide the circle into 6 equal parts.
18. Carve the second layer in the same way as the first layer.
19. Cut the soap around the second layer horizontally.
20. Cut each part into a pointed petal shape.
21. Trim the outside of the petals. Six petals of the second layer are done.
22. Divide the soap around the second layer into 6 or 8 equal parts. Then, cut the pointed petal shapes in each part.
23. Cut off the soap between the petals horizontally.
24. Slice off the bottom of the flower as needed.
25. Lower the edge between the petals.
26. Cut the soap between the petals into pointed petal shapes. These petals are the fourth layer.
27. Remove the unwanted soap between the petals of the fourth layer.
28. Trim the outside of the petals of the third and fourth layer. I suggest using leftover flakes as soap.
29. (Optional) Paint the center with yellow food coloring or soap colorant.
