So I would just get the vinyl from a local graphics shop or something. I have seen abunch of vinyl specific shops pop up seemingly over night in Corpus it seems, but will keep searching online for premium sheet vinyl graphic sheets, all I found was RealTree so far and am not going with that.
I wouldn't mind having a ski covered with digital camo, but use red, orange, and white colors so you would be high vis.
I really like this idea as opposed to painting a ski a new color. I'm sure I can find sheets of whatever pattern I'm looking for, just have to keep looking.
