I haven't played the game, but I live and hang out with alot of people who do. When my husband opened up his gaming store and our new friends caught wind of my craftiness, I got commissioned to make a Companion Cube. Now, I hadn't a clue what it was until I started researching it, but just for the fun of it I thought I would throw in a picture for you! I love your costume by the way=) You did a fantastic job.
This sucker was big too, wound up being some 9 or 10 inches wide and tall
