I have been working on "cleaning up" your t-shirt logo as suggested by tiki
in order to cost you less money for screens. This design will be 5 colors (5 screens) if printed on a black t-shirt (which most bikers prefer anyway), or if you preferred other color t-shirts (or white), perhaps the black background could be in the shape of a black kettle (which would add another color, another screen and an additional $1 to $2.50 per shirt). The screen colors would be white, yellow, red, light brown and dark brown. Obviously this version of your design is just a suggestion and you can do as you wish, but, as an example, from classb
(a t-shirt printer in Florida that takes orders online), black t-shirts with this logo printed on it would cost you $9 each (including the shirts) for 150 to 299 shirts, $12 each for 75 to 149 shirts, and $17 each for 40 to 74 shirts. Pocket t-shirts would cost $2 additional per shirt in each category.
My actual image is 5 1/2" high by 7 1/3" wide, but Photobucket reduced it to this size.
