So...I've come up with a pretty scientific way to score t-shirts (this scoring method may be similar to yours!)

5- I love it and there's a 75% chance that I'd buy it if it got printed.
4-Good print and there's a 40% chance I'd buy it for $10
3-Very nice print but I wouldn't wear the shirt
2- There's a 30% chance I'd buy it for $1.
1-I could probably find that same design (or one similar) at the mall...make it more unique!
0-I could probably find that same design (or one similar) at the mall...on the sale rack...

I have an affinity for environmental/nature/music themes.
