How do I model wings on my creature? (image attached)

More specifically, how do I model the thin bat-like part of the wings on my dragon; the skin that’s in-between the bones (zspheres)? A plane? draw topology later? How would I combine it? I’m at a loss on ideas.
Suggestions are welcome from anyone that’s done this before!
