(theres instructions out there on how to do it.)

there are some there...
and there was one more but i cant remember what site.
im pretty sure these are the better textures of the ones out (other than tony's which you wont be able to get i suppose).
look around for a jersey tutorial so you know how to change the color of the template so it still retains the actual wrinkle effects otherwise theyre going to look stupid.
