applying a fiber sheet on a surface of a prime coating layer when the prime coating layer loses its plasticity, the fiber sheet comprising fibers of a network structure;
applying a second coating layer on a surface of the fiber sheet;
exerting pressure on the second coating layer against the prime coating layer to allow coating material of the second coating layer to moisten the fibers and to permeate into meshes of the network structure, thereby forming a laminated core layer; and

wherein the second coating layer is transparent or semi-transparent.

### Claim 21 (depends on 20)

The method of claim 20, wherein applying the fiber sheet on the surface of the prime coating layer comprises applying a pressure-sensitive adhesive agent having a p aster to the prime coating layer, and wherein applying the second coating layer comprises removing the paster while at least a part of the fiber sheet retains its position on the surface of the prime coating layer.

### Claim 22 (depends on 20)

The method of claim 20, further comprising:
prior to applying the fiber sheet on the surface of the prime coating layer, applying a first coating layer on the surface of the prime coating layer; and
applying the fiber sheet on the first coating layer when the first coating layer retains its plasticity, so as to allow coating material of the first coating layer to moisten the fibers and to permeate into the meshes of the network structure;
wherein the first coating layer is transparent or semi-transparent.

### Claim 23 (depends on 20)

The method of claim 20, wherein solidifying the laminated core layer comprises:
forming one or more deeper dents at the meshes of the network structure which allow permeation of the coating material of the second coating layer; and
forming no dent or one or more shallower dents at a surface of the fibers which restricts permeation of the coating material of the second coating layer, thereby forming a texture or textures on an outer surface of the wall-cloth.

### Claim 24 (depends on 20)

The method of claim 20, wherein the fibers or the meshes spread in a 2D direction or a 3D direction.

### Claim 25 (depends on 20)

The method of claim 20, wherein the network structure comprises a 3D interpenetrating network.
