Hello and welcome to Zealot! You have come to the right place for all things paper & cardstock (and other materials and mediums), as well as model building as a whole, and to build and hone your skills. If I may ask, what genre are you interested in?
It is good to see a welder on the forum. I am very interested in seeing what all you have done!
With that being said, most any paper/cardstock template can transferred to metal (or most any other material for that matter) and manipulated accordingly!
When you start a new project, I would like to invite you to post build threads of your projects. Build threads are a great way to show off your skills and techniques, as well as to highlight problem areas that you may need help with or show how you were able to solve said problem.
So, if you have any questions, comments, concerns, need help or advice. Please feel free to ask and we will do what we can to help you (or at least point you in the right direction).
Once again, welcome aboard. I hope that you enjoy yourself here. I look forward to seeing more of your work.
