Line 2 sheet pans with wax paper, unwrap all the fortune cookies, and pour the sanding sugar into a shallow bowl.

In a glass bowl in the microwave, melt 1 bag of white chocolate chips in 30 second intervals, being sure to stir the chocolate frequently. When completely melted, dip half of the fortune cookies from the pointed end and the other half from the rounded end. Dip in the bowl with purple sanding sugar while still wet. Place on the wax paper-lined sheet pans and allow to set up.

To make the royal icing, beat together the confectioners' sugar and meringue powder with the lemon juice. Slowly add in the water until smooth and thick (the icing should not be runny).

To assemble, cover the styrofoam cone with craft paper, using tape to secure. Start on the bottom row with the cookies dipped from the rounded end. Put a dollop of royal icing on the back of a cookie and press gently against the cone. Hold for a few seconds. Repeat around the base. Allow icing to set 5 minutes before continuing to the next row. (To help secure each cookie you can also use toothpicks inserted into the cone through the fold in the middle of each cookie.) Using cookies dipped from the pointed end, adhere around the cone above the first row in the same manner. Repeat, alternating rows between cookies dipped on the rounded and pointed ends, allowing each row to set for 20 minutes in between. Don't worry if they don't line up perfectly, the spaces will be covered later with ribbon. When complete, stick 2 cookies together with icing and place on the very top. Allow to dry for a few hours.

To finish, using purple satin ribbon, start at the top and make loops by securing into the empty spaces with the pearl-topped pins. Scatter the violets throughout, securing to the cone in the same manner. Gently place atop a cake stand in the center of your table.
