Yeah, could try that. I looked into custom polystyrene packaging but you have to get quotes. I could try getting sheets of polystyrene/styrofoam and sticking them together in a block. Either way I'd have to wait until I got home for Christmas to try any of this out.
Detachable wings, I like that. Would also make it easier to take to cons and stuff. I'll have a think about this, I think it should be easy enough.
I was thinking no more than £100, though P&P would probably be quite a lot. I've asked on Brass Goggles, haven't got any replies yet.
