Method and blank for providing a customizable decorative structure

In combination, a blank for forming a decorative structure and a coloring implement for coloring at least part of said decorative structure, said decorative structure being intended to be used for decorating a supporting surface by displaying a decorative design having feature sections delimitated by an outline, at least part of said outline being intended to be colored by an intended user using said coloring implement, said coloring implement having a coloring section for dispensing a color pigmented material, said coloring section having a coloring section width, said blank comprising:

• a rigid panel, said panel having a panel first surface and an opposed panel second surface, said panel defining a panel thickness between said panel first and second surfaces;
• said panel first surface having a groove formed therein, said groove extending at least partially along a section of said outline for creating a depression in said panel first surface between adjacent feature sections, said groove having a groove bottom surface and a pair of groove side walls extending between the peripheral edges of said groove bottom surface and said panel first surface, said groove defining a groove depth between said groove bottom surface and said panel first surface and a groove width between adjacent peripheral edges of said adjacent feature sections separated by said groove, said groove being configured and sized for substantially fittingly receiving at least a section of said coloring section and for allowing said coloring section to contact said groove base wall without contacting said adjacent feature sections, said adjacent feature sections and said groove bottom surface being made out of a pigment receiving material allowing the application and retention thereon of said color pigmented material;
• whereby said groove physically separates the adjacent peripheral edges of said adjacent feature sections so as to facilitate the application of said color pigmented material on said adjacent feature sections with reduced risks of overlapping so as to allow for the sharp coloring of said adjacent peripheral edges and whereby said groove further guides said coloring section during the application of said color pigmented material to said groove bottom surface so as to also allow for the sharp delimitation of said adjacent feature sections by said outline.
