Cover a core in Duck Tape and, after poking 2 holes into the center with your thumb tack, string a piece of wire through the holes. This is the brim.
Make a piece of Duck Tape fabric that is 3 in. x 3 in.
Trace the inside of a core on the fabric and cut it out. This is the top of your hat.
Attach the brim and top to the Duck Tape core.
With small pieces of tape, attach all 3 pieces together, starting with the brim.
Continue until the entire hat is covered with Duck Tape.
Trace and cut out glitter stars.
Attach them to the hat.
Using the wire, attach your hat to the top of your headband. Reinforce it with tape over the wire.
