2. Cut the orchid and marbled-white vellum into 4-1/2-inch squares (one square for each cone). Using the scallop-edge scissors, trim two adjacent edges of the marbled-white vellum squares and one edge of the orchid vellum squares.
3. Lay one orchid vellum square on top of one marbled-white vellum square. Thread an 18 inch length of deep-rose silk ribbon onto a chenille needle, and take a 1/4-inch stitch through both of the vellum layers approximately 1-1/2 inches below the center top point as shown in Diagram 2. Pull the ribbon so that each tail is the same length. Keep the ribbon on the needle.
4. Turn the vellum squares over so that the marbled-white side faces up and the two scalloped edges of the marbled-white square are at the top.
5. Fold the sides inward so they overlap approximately 1 inch. If necessary, crease the paper at the cone bottom to aid in folding. Where the vellum overlaps, stitch one ribbon end through all of the layers approximately 3/4 inches from the top center edge as shown in Diagram 3. Stitch the other ribbon end just above the previous stitch. Tie the ribbon into a bow, and trim the ends.
6. Fold up the bottom tip of the cone approximately 1/2 inch. Thread three or four 9-inch lengths of various colors of 4-millimeter silk ribbon simultaneously into a chenille needle. Stitch the ribbons through the bottom edge of the cone from front to back and then from back to front, through all of the layers. Adjust the ribbon ends so they're even, and trim them if necessary.
7. Make a ribbon rosette using deep-rose silk ribbon and glue it over the bottom cone tip. For extra speed and ease in completing the cones, substitute purchased ribbon roses for the ribbon rosettes.
8. Using a metallic-ink pen, write the couple's names along the center front of the cone. Fill the cone with potpourri, birdseed, or wildflower seeds.
