Not surprising, I've been finding a few companies that do what I want to do: Seabags and Freitag take old sails and semi-trailer tarps and make trendy bags from it.
One idea I have is to take the old banner signs from past events. Usually I see some pretty tacky ones on bars and gas stations (in the UP at least) that are beer ads welcoming motorcyclists or snowmobilers. Or also using the nylon webbing/straps for towing.
I'm still looking tho, something not so... trashy.
