How to loft complex curves

flag.3dm (1.9 MB)

I am trying to create a cut line from a complex 3D flag mesh.

First, I traced the flag and tried to loft from the multiple curves to create a surface, but no faces made… could anyone please have a look at the file and guide me how to solve this problem? Any advices would be appreciated.
