A web for use in applying a functional material is provided. The web includes a layer that has a plurality of elevated regions. The layer defines a plurality of cavities such that the cavities are located between adjacent elevated regions. A plurality of depressed regions are located on the layer intermediate the elevated regions. The layer has a longitudinal direction and a longitudinal mid-plane defined therethrough. A plurality of functional material members are located in the cavities of the layer. The functional material members are adapted for adhesion of particles or surfaces thereon. The layer is extendable in the longitudinal direction so that the elevated regions are moved in a direction towards the longitudinal mid-plane.
