Not sure if this is the right place for this question but....
I have a rug that is about 15x20 feet. My problem is that every three weeks or so I need to take everything that is on top of it (coffee table, couch legs, entertainment center etc) off and straighten it out because it either gets tilted in such a way that it doesn't line up with the walls any longer or bunches up in the middle at certain spots.
Does anyone know of a way to keep it from moving around? Is there something I could use to attach it to the carpet below (without damaging the carpet)?
