I wish I could have taken enough pictures and steps for people to follow. I got burlap fabric at JoAnn's, it's itchy so I used liquid latex to line the inside of the mask. I cut it into pieces to form the shape of my face, and once all the pieces were done, I put them together on my face. Since they already have liquid latex on them, they kinda stick together easy but you will still want to put more of the liquid where the seams meet to hold stronger. Once you do that, you can add black string to a sewing needle and do what I did, sew the seems together for an awesome stitch look. Add fake blood for desired effect, and don't forget to paint your eyes and mouth black.
I used Ben Nye Liquid Latex - Natural Rubber Adhesive (4 fl. oz./118 mi.) to coat the inside layer of the mask (3/4 of the bottle did it for me). Use an old paint brush but not something too big that will absorb the liquid latex. I used one like this (http://www.hobbycrafttools.com/images/51%203%204th.jpg). It does have ammonia in it so I suggest doing it in a well ventilated area. Also, some people use powder after the latex dries to keep it from sticking to each other. Maybe some baby powder can help.
I used Blood Scab, which is thicker than that regular runny stuff most stores sell, i just took this picture and the blood still looks real and wet.
I looked at an old hooded sweatshirt to get the idea of how the burlap would wrap around my head. I sewed it from the top.
To get that thick string look, take black string and fold it a couple of times, enough for it to fit through the eye of a needle.
Just found this website with cheap contact lenses if anyone wants those too. http://www.youknowit.com look for Manson contacts
One last thing, i used some rope to tie around my neck and found some straw that I stuck into the mask.
