1. Once you have a printed picture, grab your ink pen and a ruler, and get to tracing. One tip we can pass on is to trace very slowly, this will give the pen's ink more time to soak into the paper and also help you make straight lines. Also, if there is something you want to shave, then just don't trace it. Kind of like what we did with the extended cab portion of this truck, we wanted to see a standard cab longbed so we just made it.
