custom speaker socks? anyone?

Anyone know where to get custom speaker socks made? My old acoustats are looking really ragged. i actually found a place that makes socks for these speakers but dont have the color i want. just wondering if anyone has any ideas on this. Do i need to make sure i get a certain type of speaker fabric? can i buy this somewhere and then take it to my local upholstererererer?
as always, thanks in advance.
