Print All Over Me
I haven't purchased anything from PAOM yet... but I want to. Max and I have definitely talked about wanting to start a website just like this. Basically you can upload an image to print "all over" different basic items of clothing. You can also choose from other peoples designs. My favorite item to customize is the shift dress. It's kind of pricey, but I might have to treat myself some day soon.
Newhive is the website that I actually have some experience with. This is very similar to to.be, except without the ability to print your design to a shirt, and instead of a "field" you make an "expression". That has it's own advantages to it though, like theres no incentive to make the "expressions" except for the sake of art. And I am all about that. It's a diverse cyber gallery. Also there are more things you can insert into your expression than you are able to at to.be, like music and video. If you want, you can check out my Newhive profile here.
