Trev, as long as you've gone this far, you might as well add the in-and-out fabric that criss-crossed the length of the wing. It would weight next to nothing (bits of black crepe paper might even work) and would make the wing look even more fantastic and even more authentic than it does now.

The compass really does look good! I'd say it's time to start getting some covering on that puppy! Remember that according to Dave Platt once you've covered the model you're exactly half finished!!!
