Truth be told, I just really like wearing things that I designed myself.
I got a few requests from friends who wanted to get some of my designs on their clothes, and heck, here we are now.. selling things on the RedBubble.com market!
RedBubble uses really nice quality shirts from American Apparel, and so far I've been extremely happy with every shirt I've ordered from them. RedBubble is also really good to its community of artists/creators and treats us very well. Before I happened upon RedBubble.com, I tried Cafe Press and Zazzle; my thoughts on those two now:
And now one last plug for RedBubble, taken from their own site:
RedBubble allows you to sell your work with zero hassle, supply us with a digital file and we'll take care of all manufacture, shipping and customer service. From cards to t-shirts via stickers and framed prints, not forgetting calendars, canvases and posters, we really do have more high quality products than you can shake a large and unruly stick at.
TL;DR: I like t-shirts and decided to start selling some, just for fun.
