It is interesting to me that Teespring seems to force sellers to advertise each specific design. I was looking for, but couldn't find, a way to see all designs created by a specific user. On a cursory search, I found a few designs by the million dollar seller mentioned in the article, and each of those designs involves clip art quality graphics and a number of seemingly randomly chosen fonts. I imagine if I came across a page showing all of his designs, Teespring would look a lot more like Zazzle or CafePress.
here is an interesting writeup from someone who is making money doing this: <a href="http://getbusylivingblog.com/how-ive-profited-100k-online-in-just-5-months-this-year/" rel="nofollow">http://getbusylivingblog.com/how-ive-profited-100k-online-in...</a>
So, what happens if Facebook decides it doesn't want to allow Teespring ads anymore? From what I can tell it is very heavy skewed towards FB ads. This seems very risky to depend on one channel for sales.
Society6 seems to be way ahead in terms of the number of product lines.
