House Baratheon of Dragonstone

my Halloween costume this year is Melisandre of Asshai from George RR Martin's "A Song of Ice and Fire" series (the series on which HBO's "Game of Thrones" is based.) I thought my costume needed a really cool prop, so I decided to make a banner with the sigil of the king she serves (Stannis Baratheon.)

To make the sigil design, I combined the description of the sigil from the book with the illustration in the back of the book (the difference being a full bodied stag as opposed to just the stag's head.) The description just said it was the crowned stag of House Baratheon within a fiery heart, to show Stannis's allegiance to the new religion of the Lord of Light, R'hollor.

I found my own design of the fiery heart, and then used HBO's version of the House Baratheon stag and combined then, then traced the design onto the material and painted it.
