This one would be much too difficult to figure out a tutorial for, but I can give some basic instructions on how to make a mask.

I find a base first, and I paper mache the base, and then I trace what shape I want the mask to be and cut it out once the paper mache is dry, and then I just made my mask. glued on fabric, sewed on beads and I think I actually had to use just a regular craft glue for this and then I bought a hot glue gun and realized that they're amazing and I can't live without it now. :)

yeah I know that sucks as a basic tutorial but if anyone wants some actual instructions just ask. :) I even found a better way to make masks now than paper mache and I'm leaving the link here because it's a cool tutorial that a friend showed me and it made mask making a hell of a lot easier. :)
