I 've decided that I wanted to start making life-size Kanohi Mask. I was really excited to start my first mask when I realized: How am I even supposed to this? I don't even know what to make it out of! Any tips would be greatly appreciated. Thanks!
Start with one of the original Mata masks, i Suggest the Hau 
Cardboard, duck tape, spray paint and maybe add some lenses like Eljay's Miru has.
Since it's Halloween season, you could get a basic costume mask and add to it and modify it into the proper kanohi.
Paper mache, wire frames and plaster of paris. nuf said.
In the middle ages you had to make a masterpiece to become a master. What about making a mastermask and then getting the job?
Can we get @Eljay over here to offer his thoughts? I myself have never done anything like this so I don't have any tips. :/
I'd be of no help here, sadly. =P I just picked up a Miru, and started carving the shapes out of cardboard. It's why it looks so bad. I just had to wing it, and once I had a version that looked right and fit, I painted it.
Looks bad? Why, I've never seen a better cardboard Miru myself!
And I found that it was great fun making my plaster Akaku Nuva. Took forever and eventually broke because of misuse.(cough siblings cough) If I had any good pictures of the mask and the process I would definitely post them for you. Maybe this year I'll make the new Akaku...
