Find a local upholstery shop that does auto. Tell them what you want and they can include it on their next order. My local area has truck delivery from the supplier to the shops almost daily. Next option would be to do a Google search for "Upholstery Supply" company. Luckily I have a supply house about 45 minutes away and they sell to anyone who comes in and are very helpful to those who may not know exactly what to ask for.
