Jon writes: Hi AT, I have an old tan colored leather couch I got from a friend who recently graduated. It's basically been through the war, and looks pretty bad now. I've heard about leather dye, would it be possible to dye the couch to a darker brown in order to cover the wear and tear? If so, is this a project a novice could conceivably take on? From what we've heard, dyeing any leather(couch, shoes, etc...) should be left to the professionals. However, that doesn't mean it can't be done. Does anyone have any first hand experience to share with Jon?
