Here is how it is done:
What you need!
Start by taking the felt and fold it over to match the other side of the felt.
Cut a cone shape from the folded piece, and use hot glue to close the cone.
Turn the cone inside out and cut small slits on the bottom. Then glue the small flaps together to form a base (sorry the picture is blurry!).
Cut a circle for the brim of the hat. Also, put a small circle in the middle, so you can stuff it! Glue the cone to the middle of the circle.
Put some stuffing in the cone, so it keeps it shape.
Glue the headband to the bottom. Then glue a piece of circle felt to cover the hole and secure the headband to the hat.
Add some cute accessories, and you have a simple hat!
