From deer hide to bucksin - start to finish

Although he's using damp straw, punk wood works even better and it gives your bucksin a nicer color.

If you don't have eggs and you hunted the animal, you can use it's brain. It's gruesome but such is life. Boil the brain in water while squishing it in the pot so that it produces a white-ish greasy substance. Apply it with your hands on the hide while it is still stretched, on both sides. Some people add soap to it as well, it should be okay if you don't have any or if you use liquid woodash soap.
