Keep in mind that I made this instructable after I made the mask and I barely documented the construction process so I recommend using this instructable in conjunction with some other, more general, leather working instructions (some of the steps are simplified or unspecific because I don't know how work with leather properly, nor do I have the tools to do so). Sadly, plague doctors aren't very common costumes but they do pop up in videogames and things (Shovel Knight and I think there was one in Assassin's Creed) I made this mask with a lot of help from the people at Tandy Leather so some credit goes to them as well.
The idea was that herbs would be kept in the 'beak' to purify the stale air.
The creepy outfits were meant to protect against Miasma, or foul air, that was thought to cause sickness at the time. Historically, plague doctors were hired by the government to treat the Bubonic plague.
