I made the MG's straps from foil:

I got the foil from one of those foil etching sets. I got the idea when I saw SWMBO's god-son doing one. The foil is pliable and a bit tougher than the tin-foil we get down here.
You can use miliput, or any modelling epoxy, but the key there is to work it and get it into shape and position before it cures properly.
