Weird Request

The electric reclining couch is not adjacent to any outlets.  An extension cord is an obvious trip hazard to people and out of control dogs.  The ideal solution a 2' extension cord that is very, very flat.  I could tolerate one a color that is not camouflaged to the walnut flooring (which is absolutely beautiful), but the wife will not. Do you have a source for one that is really flat and could be held down by walnut colored tape.  Does anyone make walnut grain tape?
