16. An embossing guide as claimed in claim 1, further comprising a first embossing guide alignment indicator disposed on the upper side of said embossing guide configured to instruct the user on the proper side of a folded said sheet media for use with said embossing cutout.
17. An embossing guide as claimed in claim 16, further comprising a second embossing guide alignment indicator disposed on the lower side of said embossing guide configured to instruct the user on the proper side of a folded said sheet media for use with said second embossing cutout.
18. A method for mounting a display item on a sheet media, said method comprising the steps of:
selecting a punch tool an punching a slit into said sheet media;
selecting a corresponding embossing guide for said punch tool and embossing a design into said sheet media wherein said slit is aligned along at least one edge of said embossed design; and
mounting said item for display by placing a corner of said display item into said slit.
19. The method for mounting a display item as claimed in claim 18, further comprising steps of repeating said punching and embossing step for each corner of said display item.
The claims below are in addition to those above.
