1. A process for deforming a web, the process comprising the steps of:
a) providing a precursor web comprising a first layer and a second layer, the precursor web having a first surface and a second opposing surface,
b) weakening the precursor web at a plurality of locations to create a plurality of weakened, melt-stabilized locations in a first area of the precursor web where both the first layer and the second layer exist;
c) forming a plurality of first features and a plurality of second features and a plurality of third features in the precursor web simultaneously,
wherein the plurality of first features are formed coincident with the plurality of weakened, melt-stabilized locations in the first area of the precursor web, andwherein the plurality of second features are formed in a second area of the precursor web where the second layer does not exist, and wherein the plurality of third features are formed in a third area disposed between the first area and the second area, where the first layer and the second layer exist, wherein the plurality of second features extend in a first direction away from the first surface, wherein the plurality of third features extend in a second direction away from the first surface, and wherein the first direction is opposite the second direction.
