Fabric Cowboy hats

I'm toying with making cowboy hats. You wouldn't think it's that involved but I'm drafting a pattern and running through test runs.

So far I've broken 3 needles and had to repair the sewing machine. 

I think some of that is my fault but... That is learning 

This run was with batting. I have some heavy stabilizer I think will be a lot better. 

i just safety pined the sides up to see what I thought.
