FuturenautTees.com is ours! So far I'm really happy with how the website is working and looking. I'm sure I'll eventually want to switch the shopping experience over from Etsy to a shopping app on this site, but for now this works fine. I've been really happy with Wix, which is what I'm using for the site in regards to both design and management. I know, I lose geek points for not coding the site by hand. It's just something I didn't want to bother with.
Also, the first episode of The Futurenaut Tees Story is up on the YouTube channel, and I'm really proud of how it turned out. It goes over what led to the creation of Futurenaut Tees, what the creation entailed, and what the first week was like.
