Slipknot percussionist Shawn “Clown” Crahan wants fans to send him mask designs.  A tweet from the masked-band’s Knotfest account asks fans to send mask designs to Clown’s Knotfest email address.  The contest has no time-limit, and those who create Crahan’s favorite masks could be asked to join him on a livestream where he will wear fan-designed masks.  He says they can be designed from scratch or by using an already-existing mask as a template.
