Here is one that I worked with. I tried to feather the colors so that the lines had contrast and depth. It's a work in progess but this will take a while once I get down to the pixel by pixel level. It was tough to get rid of that watermark.
I think you did a fantastic job with that logo so I'm not sure if I'm wasting my time or not. I should just cut out what you already have. But...that wouldn't be as much fun.
In any event I'll make two sets of jerseys. One with your logo and one with this one once it is complete.
Anyway here is what I am thinking of using for the cap.
