Holy crap, I love your super mario block pillow! thats is sooo cute! And its for a good price. You have some good things on there so far. And video game items/geekery go far on etsy.
Your pictures look good as well. Simple and clean with the black backdrop. Keep adding more to your store and you should get some sales in no time, even though its hard to do at first the more you have in your store the more people will flock to it. :)
