I don't have much experience making props, let alone from scratch. So I'm planning on using one of these as a base and either re-bending the bow into the right shape or whittling/sanding down the parts that I don't need and build up the parts I do need with paper clay (like the medallions on the ends). I'm leaning toward the third one because it looks like it would be the easiest to modify.
Any tips on modifying or making one would be welcome, too!
One of the most basic rules for survival on any planet is never to upset someone wearing black leather. (This is why protesters against the wearing of animal skins by humans unaccountably fail to throw their paint over Hell's Angels.) -- Terry Pratchett
