When putting carpet in a room, if a small, square area of hardwood is left in front of the entry door, does that have any bearing on the future quality of the carpet? Someone told me that areas like that were more difficult to get a stretch to remain tight and that the carpet might be more likely to wrinkle as time goes by as opposed to laying it wall to wall. Also, what is a good quality carpet. Not something that would go in a mansion, but just good quality for an average Joe like me? Is Berber a good type?
