dayc-tpl02 : 5 - The first template, frames. I did choose double scale, you can choose whatever as long as you use same scale for all templates.. As you can see on first picture above, I have added three more extra frames compared to the original plan. If not, the skin will hang loose and most certanly deform in shape after a while. (Note Frame 1 and 2 did not work to make asis in double scale, therefore I have made them somewhat curved. Maybe you need to make yours even more curved than I did. )
