Place your rolled out cookie dough on your cookie sheet. Place a sheet of parchment paper or a silicone baking mat under your dough. Using a thin knife, trim around your template, cutting out your necktie in cookie dough.
Baking times will vary from oven to oven. These cookies baked for 9 1/2 minutes, but I began checking them at 8 minutes. You want the edges to be just turning brown. *This is a BIG cookie. If it is too soft it won’t hold up to the royal icing.
Now pick up the card stock and place it directly above the line you just made. Using your light blue piping icing (in a pastry bag fitted with a #2 tip), pipe a line above the card stock. (The dark blue line is now directly below it)
Using the template will ensure that your diagonals are both equally spaced and straight! Continue moving up the tie, alternating colors as you go. When you get to the top, draw a horizontal line at the bottom of the knot.
Make sure you draw the stripe on the knot in the opposite direction! Connect your stripes along the outer edges with alternating colors. Once you have completed all the lines, let the cookie dry for approximately 30 minutes.
For the knot, use your light blue icing and a #2 tip. Pipe a horizontal line where the knot meets the body of the tie. Then, outline the edge of your cookie, alternating the colors so they match the stripe. Let it dry a few hours, overnight if you can.
