Here is the final mask in the Death Eater mask series. Some officially licensed product manufacturers list masks similar to this one as "Bellatrix's mask" while other sources indicate that a mask design like my papercraft Death Eater Mask #1 is the mask of Bellatrix Lestrange. If there is a Harry Potter fan out there who can clear up this discrepancy, please let me know. :) The template for Mask #7 may be downloaded here.
UPDATE 7/15/2011: This is no longer the final mask in the series! ^^ There are now Mask #8 and Mask #9.
