If you are dressing up as Dr. Seuss' infamous Cat in the Hat, you can make the trademark bow tie from felt and cardboard. With a few simple instructions, you can make a bow tie sized for an adult or child. After the tie is completed, clip it on to your outfit, or add a piece of Velcro to the back of your tie and the other piece to your costume.
Measure for the bow tie's width. This will be determined by who will be wearing the tie. Measure the distance from the tip of the wearer's right ear, to the tip of the wearer's left ear.
Measure for the tie's height. Each end of the bow should be about half the height as the entire bow's width. For example, if the width of the bow tie is 30 cm (12 inches), the ends of the bow should each be about 15 cm (6 inches).
Cut three identical bow shapes (similar to those in the image). Cut two from red felt and one from cardboard. Use the measurements from step 1 and 2.
Glue a red bow shape onto one side of the cardboard bow, and the other felt cutout onto the opposite side of the cardboard bow. Allow to dry.
Cut a third bow shape from red felt. This should be the same width as the first bows, yet about half the height.
Fold the narrow bow in half.
Place the narrow bow over the centre of the cardboard/felt bow, and let it hang down. Glue it into place.
Glue black trim along the entire perimeter of the bow tie.
