This Halloween, make your own Disney Aladdin Costume! Instructions: Use red paper and gold string to create a tasseled hat. DIY your own vest by using blue fabric. Fold in half and then cut out arm and neck holes. Use hot glue to glue the sides together. Fold over the bottom edge of the pants and use hot glue to make a hem. Leave an opening so you are able to insert elastic. Use hot glue to attach the ends of elastic together and close up the rest of the hem.
