Abstract
A method for increasing the thickness of a fibrous sheet including stretching the sheet beyond its relaxed length and returning the sheet to about the relaxed length, causing the sheet to have a second thickness greater than the first thickness. The sheet can be a wet-wipe. The wet-wipe includes an elastic layer and a fibrous layer, which increases in thickness when stretched then relaxed. The wet-wipe can be stored in a container which causes the wet-wipe to stretch as it is removed from the container.
