Notes: use a computer, photographes, drawings, whatever, make it the standard 5.5"x4.25" (landscape or portrait) spokecard size.
if youre doing your design on a computer, please use 300dpi or higher and print it on a good paper.
all spokecards must be laminated (1/4" laminate extra on all sides is recommended regardless of how you make your spokecard).
