Yep, and don't know if this is good or bad but most of the burlap you'll find at the fabric stores is of a much better quality than what they put in the seats of several hundred thousand cars back then and even now (if they still even use burlap?) Oh and you'll have to pay the price.. but it's really not that expensive
