The YouTube video channel contains several tutorials showing how to make a hollow mask from papier mache. The eHow and Instructables websites also give information on how to do this.
Renji? No, he isn't part hollow so he can't get a hollow mask.
Ichigo doesn't have his hollow mask in Shattered Blade but he does have it in Versus Crusade
you have to kill your hollow inside of your mind
No, She is a Human.
So far (atleast as far as chapter 399) it hasn't been comfirmed yet. Well Aizen did say when it was revealed when some he new had a hollow mask that he is to good for a hollow mask, he goes on to say that only a weakling would need one.
It's simply called a Hollow mask.

Mask? What mask? There is no mask that you have to find in Shark Tooth Island, Poptropica.
