Changing humidity or temperature, as well as storing a rug rolled up, can cause the edges of a rug to curl. The type of weave or edge binding may also contribute to this problem.
Curling occurs at the edges or the corners of an area rug. Sometimes only one side or corner presents a problem.
Using a rug pad or taping down the edges of the rug will help prevent the edges from curling.
Before laying down your rug for the first time, reverse roll it and let it sit that way for a few days. This will train the edges to curl down towards the floor and not up away from the floor.
Curling edges on a rug provide a tripping hazard and should be remedied as quickly as possible.
Re-sewing or rebinding the edges of your rug may be done if the above methods fail to remedy the curling edges.
