Method for period horn work
Horn was the plastic of earlier times. Once cured and cleaned, it can be worked endlessly into almost anything. You can make horn cups, spoons, inkwells, combs, salt and spice horns and almost anything else including, of course, hunting and powder horns. It is more or less compressed hair, like toenails and hooves, it requires different treatment and methods than bone, some are close to woodworking others aren't but all the methods are easy to learn.
