I have always used area carpets on my hard wood floors - evening in my large kitchen.
The small area rugs were meant to be placed in front of narrow French doors into the dining room and one rug in front of the sink area.The rugs were so thin and generally so poorly sewn that I felt as if I was placing a limp wet rag on the floor. I will consider ordering carpets more thoroughly in the future. I wasted my $50 - a slight amount, I know, but it was wasted.
