About a year ago, I made Ulquiorra Schiffer's Hollow mask. It was one of those rare creations that I actually liked, and considering how hard it was, I decided to make a tutorial. I included all the information I could think of, but since it's my first tutorial, it will undoubtedly be missing things.
If you have any questions, please comment! I only wish to improve!
Tools: (for tutorial) Photoshop Elements 8, camera
(for mask) Fast Mache, wire mesh, silk ribbon
