  4. Insert a red, white, and blue LED through the felt from the front. Fold the legs flat with the shorter, negative leg touching the top row of Maker Tape. Fold the longer, positive legs down toward the bottom of the big piece.

    • Fold the legs flat with the shorter, negative leg touching the top row of Maker Tape.

    • Fold the longer, positive legs down toward the bottom of the big piece.

    • Secure the top legs with a few pieces of Maker Tape, and place one piece of Maker Tape under the bottom legs. (This will make more sense in the next step!)

  5. Add a "tail" of tape to each of the three LED legs by removing the backing from only the first inch of tape and sticking it in place on top of the LED leg. Then, twist it so that the adhesive is facing up instead of down. (photo 3) Then, twist it so that the adhesive is facing up instead of down. (photo 3)

  7. Stick the Maker Tape tails coming from "U", "S", and "A", to the hat as shown and trim any excess. The fourth piece of Maker Tape is touching the positive side of the battery. Cut a strip of felt and stick a piece of Maker Tape to it as shown, then attach that piece to the positive piece. Glue the piece of felt with a dab of glue on the left side to create a slider switch.

  8. Slide your finger over the piece of felt on the brim - when you are near the "U" the red LED will light, the "S" the white LED will light, and the "A" the blue LED will light.
