this is the preliminary stage in my plague doctor mask, It is basically a paper beak taped to a plastic blank mask. I widened the eye holes out with just a pair of scissors before inserting the top of a bottle into one (I used black electricians tape to cover the sides of the bottle as well as thicken it a bit)

photos taken on a panasonic SDR-s7 video camcorder in still mode and compiled together using MS-Paint

work took about an hour to go through 3 beak designs before this one
