If you want cheap and easy, I can show you that. If you want "looking good" close up, well, stop being so damned picky. The decals I made for my Super Cub were just stolen images from the internet (open source-leave me along copyright police) printed on photo quality paper. I bought super thin, double sided sticky stuff at Michael's to adhere.
They looked great until you and I went flying in the snow that day.... Now they look AWESOME! Tye dye AAF insignias!
