Has anyone dealt with TeeSpring? (Off-Topic)
I have my reasons for asking. :)
Other suggestions are welcome.
Has anyone dealt with TeeSpring?
Personally I like Spreadshirt if you want something quick and easily customizable. Haven't used TeeSpring at all though, although it looks like it has a lot of customizability as well from just looking at it briefly.
I have a hoodie from them...
...which is a good quality one. But I have not done any custom things and I cannot speak for their shirts.
