The leather came from Tandy's, from their scrap bin actually... They sell it by the pound, so it wasn't much at all
Oh, sure... You can get any kind of leather from them by the square foot from their site. As far as scraps go, you can buy a "remnant bag" online, but that is a crapshoot on what you'll get, and if you'll get matching pieces. If you have a store near you, I would think that would be your best bet
Awesome prop, damn well done!...and painted today! Just need to add some trim to finish the base and paint it!
