Tricorn hats

So I have an idea in my brain about a tricorn pirate style hat. I looked into custom ordering it but after talking to 3 different places, no one wanted to take on the project (not for less than stupid money)
So now I'm looking at doing it myself which honestly I'm more comfortable with because then I know it'll at least be able to adjust/add/etc during the build.
ORIGINALLY I had thought of using lightweight leather with a breathable cloth liner. Now I'm wondering if Felt might be less "brain baking hot". Black cloth vs black leather.
Anyone have experience with making hats?
I'm assuming Felt would be easier to work with but Leather would be nicer/last longer...
Just trying to gather information before diving into this particular mess of things...
