Actualy this is a post lofting question. I am nearly done lofting the forms for Nick's Guillemot double (not a bad process once you have done a couple) now I am wondering what is the best, most accurate method of going from the half forms I now have to the full form. I know that I flip the sheet to make the other side but how then do I draw it? I have thought about carbon paper or cutting on the line and drawing around the cut out. Each of these seems to have some room for error. What works for you guys? THANKS
