Im making a katana, and modelling the wrap that goes around it. I finally got the shape down but i cant use shrinkwrap to shrinkwrap it to a cylinder because it comes out weird like this
Extruding wont help, heres what it looks like before:

one half of the mesh is supposed to be on top of the other, and when i shrinkwrap it, it turns the shape into a cylinder type and takes away the overlap. I can't use the curve modifier because it messes it up too.
