Revelations 12:3 (YLT) And there was seen another sign in the heaven, and, lo, a great red dragon, having seven heads and ten horns, and upon his head seven diadems. 

This pattern has just four of the heads of the dragon.  Another version (larger and more complicated) can be found by clicking HERE.  Or another on this site also.  This wouldn't be a pattern for anyone "faint of heart" as there are many complicated cuts and pieces.  But its going to be a show stopper when finished.
