UV unwrap

I am a beginner at blender and I just want to model and texture this hat I made, I don’t know how to UV unwrap, I would really appreciate it if some one else could do it for me! Thanks!!

there you go, updated file, edit model slightly since it was a mesh… made some more quads, learn about seams, and learn about mesh editing, you dont need to create inner shape, there is a modifier to give thickness to things like this.
