Hey Skippy,
If you're using tracing paper, why can't you just make 2 copies of your pattern and use 1 as a left and 1 as a right just by flipping it over?
I haven't done a double rig myself yet cuz I'm more into the historical correctness of things. Carrying that much iron around your belly gets
heavy very quickly.
As far as people critiquing your work, you are your own worst critic, but from my own experience, I believe I've learned more in my life
from those who drove me hard because they saw potential and I still carry a wealth of knowledge from those old hard asses.
You'll learn !!!!
