wind mill blade design?

Im currently building a windmill, and For the blade design I was thinking about going with something like this: https://www.instructables.com/id/Ted-Baer-s-Bicycle-Wheel-Windmill/  and I could use some help with figuring what the actual shape of the blades would have to be cut into, to fit onto the rim. thanks:D

Look at that link again, you can see the sort of shape you need. Try cutting card as prototypes and you should be able to work it out for your wheel.
