I am using these rugs in my laundry room and family room by the doors to catch dirt, leaves, grass etc. before they get in the rooms.  I really like them because they are cotton and washable but apparently my dog likes them to chew on too!  It is very hard to find low profile cotton rugs (washable) to fit the places I needed but these do the trick (except for the dog thing!).  I really didn't need the popcorn feature but they're OK.
