I'm disabled, with very poor balance, and have serious trouble walking. I have to be very careful not to trip and fall on the edges of area rugs, among other places. One rug we have just would not lay flat and I stumbled over the corner several times -- although I did not fall. I got these short double-sided rug tape strips and put them town on the offending corner. I have to say it worked perfectly, exactly what it was supposed to do. Highly recommend. Be sure to wipe the floor clean of dust and brush off and loose dust and threads on the bottom of the rug corner.
