Adding more possibilities to Tee Virus

I know Tee Virus is slowly growing and it takes some time and money to make this site even better, but here are some of my suggestions:

1 - Create possibility to choose the side(s) of the shirt you want to see printed.
This way you can make some jokes that are only fun when you read both sides
2 - The designer can give preferences for the color of the shirt
Some designs just don't look good on white, and some people just like to wear black or something more colorfull. So black would be the most obvious and most important addition as a color.
3 - Let the designer create more exact measurements and location for the print to be placed.
At the moment, your design will be centered horizontally and the vertical location seems to be measured from the middle of the chest. It would be nice to have a possibility to, for example, create a 1to1 heart at the same spot your real heart is.

All these changes would open the door to a lot more creative designs, I think.
Thanks again for the great website and the great idea of letting us earn money while helpen Videosift!
