How can I make a sketch wrap around a non-cylindrical surface?

I'm trying to make a detail on a helmet that wraps around the side of the helmet (similar to the vertical one in the picture), but I don't know how to do that and the wrap tool doesn't work because its not a cylindrical surface. How can I do this?

You can project a sketch onto a surface with a projected curve. If you make a sketch in another plane, you can select that sketch and the edge of another sketch (like the bottom curve of the helmet) and it will wrap your sketch onto that projected surface.

Unfortunately, there isn't much you can do with a projected curve once it's made. If it's closed, you can turn it into a surface. But you can't use it to extrude or split.

@arthur_nichelson you can't currently wrap a sketch onto a non-cylinder, but a workaround is to create a cylinder to approximate what you are wrapping to and then wrap to the cylinder (using thicken to modify your solid), like this:
