C is for Coven from A Dark Alphabet designed by Julie and Becky's Note of Friendship blog.
A coven is a group of witches of any number from three to thirteen. Once the coven grows larger than thirteen it will split into two smaller covens to keep the number manageable. One of the most famous covens is the trio of witches that Macbeth encounters on the heath who give him the prophesies that ultimately lead to his downfall.
And what does a coven of witches need to cast their spell? A cauldron, of course! A cauldron is simply a cast iron pot found in many homes in the past, used for cooking or maybe boiling up herbs and potions. Like the broom and the cat a cauldron could be used as "evidence" by the Witch Finders that an innocent old woman was in fact a Witch!
I found lots of lovely cauldron patterns online:
