There are some upholstery repair shops that can take care of that. Had a nasty tear done to a leather side panel on my wife's (former) Jag when the sharp edge on my wristwatch band cut a 2-inch gash.
Cost me $120, but you can't see that any damage was actually done...I never told my wife about it either...just quietly had it fixed!
