Surveys have been sent out to the supporters of this ideas to see exactly how they want this implemented.Mr. Maal commented
Though I have voted this idea for once but I had to Vote for the idea of "Woocommerce Custom T-Shirt Designer" for 3 times. Because it simply won my heart and Love.
You can check the details of that idea at : http://ideas.woothemes.com/forums/133476-woocommerce/suggestions/4304361-custom-t-shirt-designer-for-woocommerce
And the more interesting thing is, I saw that same idea published in codecanyon at the following link : http://codecanyon.net/item/woocommerce-custom-tshirt-designer/5185471?ref=wpproducts
And that made me more excited to see it in reality.
Guys you can check it out too and Vote for it at least twice to encourage them.
