Choose two pieces of construction paper. Ask the child what her favorite color is to ensure she likes her crown.
Cut one of the pieces of paper into 2-inch wide strips. Line the strips end-to-end to make one long band. Attach the pieces to one another using transparent tape.
Wrap the band around the child's head so it covers his forehead. Make a mark about 2 inches beyond where the ends of the band overlap at the back of the child's head. Cut off any excess paper beyond the mark. Lay the band out flat on a table while you decorate it.
Trace six 2-inch squares on the second piece of paper. Add triangles to the top of each square to make shapes that resemble small houses and cut out the shapes. Tape the bottom of each shape to the inside edge of the headband so most of the squares stick out the top of the crown.
Decorate the crown by writing the child's name on the center of the band using glue. Sprinkle glitter over the glue to make the name shimmer and shake off the excess glitter. Add stickers to the crown or draw on smiley faces using markers. Let the glue dry completely.
Tape the ends of the band together. Use two or three long pieces of tape to ensure that the crown stays together all day.
