Check out this fabulous video on how to make an easy Minecraft Halloween costume.
My eight year old son is completely absorbed in the Minecraft game now. And he spends his spare time watching YouTube instructional videos about the game. Minecraft is arguably the best video game to come along for kids in the past ten years. It's a virtual version of Lego and lets your kids be infinitely creative. It's become a huge cult favorite. It's approaching the popularity of Angry Birds..
If you're looking for a cheap Halloween costume for your boy(s), this is definitely one to consider making at home. (Also your kids will really enjoy watching the virtual world play at the beginning and end of this video).
