Here is a cool lesson on another Game of Thrones house logo. This will be my final tut on how to draw the House Greyjoy logo, step by step. Now this one of the Great Houses of Westeros and it rules over the Iron Islands. House of Greyjoy has a sigil that looks a lot like a squid, but it is in fact a golden colored kraken on a black canvas. Drawing the House of Greyjoy logo shouldn't be too complex. It will be fun because making any house logo from Game of Thrones is.
