Just trying to find a source for some oak or mocha colored carpet, to cover a box. Anyone find anything that matches well?

 

I haven't personally looked, but Select Products has a ton of different high quality carpets and vinyls.

 

Theres a lot of variance in tan/oak/beige out there...

go to the local upholstery shop or fabric store (make a few phone calls to weed out the ones that dont have what your looking for) that carries automotive carpets and vinyl and select from "off the roll" or from a sample book that you can take out to your car. If you have to order it sometimes they make you buy a whole roll rather than a yard or two.

I got some Vinyl doing this from a local fabric and leather "emporium" (ie. they had stuff piled high and deep everywhere in utter chaos) and was able to get a very close match to the plastic interior panels.
