the rounded perimeter corner is rounded with a radius in a range of 2 to 50 millimeters.

9. The decorative article of claim 1 wherein:

the slot corner is a rounded corner; and

the rounded slot corner is rounded with a radius in a range of 2 to 50 millimeters.

10. The decorative article of claim 1 wherein:

the slot formed in the rear side of the substrate follows an outer contour of the perimeter side of the substrate along at least a portion of a perimeter side wall of the substrate.

11. The decorative article of claim 1 wherein:

the slot formed in the rear side of the substrate forms a continuous loop.

12. The decorative article of claim 1 wherein:

the substrate is hollow.

13. The decorative article of claim 1 wherein:

the substrate is one of a blow molded substrate, rotational molded substrate, thermoformed substrate, compression molded substrate and a foam molded substrate.

14. The decorative article of claim 1 wherein:

the substrate is formed of at least one of rigid foam and a honeycomb core.

15. The decorative article of claim 1 wherein:

the first decorative covering is a woven or nonwoven fabric.

16. The decorative article of claim 15 wherein:

the fabric is a carpet.
