Ok first a bit of text.
1. white sheet of paper or 3X5" card one or the other it won't matter.
2. draw a line veritcally (north to south).
3. Lay your prop down, center it on the line with blades at horizontal. (East to west).
4. Mark on the paper the end points of each lamination.
5. in #2 pencil mark on the edge blade / paddle the same as #4.
6. Your propeller should be a base colour of varnished wood.

7. On the front face of the paddle apply your darker lamination colour like a narrow Nike swoosh icon.

8. From the paddle edge the lamination narrows down to the prop hub in a narrow stripe.
9. Photo references that I have posted earlier should be reviewed.
10. After dry use clean thinner in a brush to straighten the dark lamination edges. This also adds wood grain to the base colour.
11. Once done rotate the other blade / paddle to the same loction and duplicate 4-10.
12. Once dry flip over to the back paddle faces and use the dark lamination edge on the paddle to bring more dark paint down to the propeller hub.
13. After dry use clean thinner in a brush to straighten the dark lamination edges. This also adds wood grain to the base colour.
14. Rotate to the other paddle / blade rear face and repeat.
