Because of this a Plague Doctor's costume is creepy - also with the added benefit of it's resemblance to both The Grim Reaper and Ravens.
Step 1: Pre-Construction
Then trimmed and shaped it to provide a snug fit to my head.
Step 2: Cutting & Arranging
The resulting template sections are traced onto the mask material and cut out.
I constructed mine out of light-weight foam paper. This foam paper is available in 12"x18" sheets at most hobby and craft stores.
Once the individual pieces for the mask base were cut out they were assembled and holes were punched along the seam using a tiny hole punch.
I used paper brads to hold the sections together to give the look of rivets instead of stiching.
Step 3: Attaching Straps
Once the base of the mask was complete I cut the forehead and side straps from craft foam -
Two pieces were cut about an inch wide and (one) the length from ear to ear, (the other) from forehead to nape of neck.
First, a long vertical strap was attached at the top of the head using the same rivet technique from before. The base of the vertical strap was then looped
back on itself so the horizontal strap could pass through it. The horizontal strap was then threaded through the vertical strap, and riveted at each side
of the mask.
