DO NOT BUY THE RUNNERS. I way a bit concerned when I opened the package. My previous natural runners were fine and lasted over a year. They just got dirty so I wanted a replacement.
THESE barely stay together! They are not stiff at all. So I am constantly straightening them out, and YES I have rug pages under them. 
They are falling apart. They are only two months old and need to go into the trash. Very very disappointed and I rarely right reviews. BEWARE.
Also, they have a lot more orange in them then the picture shows.
