How to Make Templates for a Fursuit Head?

I have read that making and using templates when carving the foam for a head is extremely helpful for accuracy, exactness, symmetry, and general simplification of the construction.

I want to make my own templates for my red panda fursuit head, instead of printing off a pre-made one. (I value originality, and also I doubt that there are any printable red panda templates anyway)
However, I have been unable to find a tutorial on how to make good templates.

May I get a general idea of how to make accurate templates for a red panda fursuit head?

Thank you.
