I found a leather piping supplier on eBay:

They have black, dark brown, and saddle tan. Just ordered some, and will let you know about the quality!
There are also several suppliers on eBay selling vinyl piping, some have a nice matte finish: http://www.ebay.com/itm/360391134590?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 . I just ordered red and white, and will let you know about the quality on this one too!
Cheers!
