Papier-mâché tiara is like making a crown out of paper. You start by cutting strips of paper and dipping them in glue. Then you stick the strips of paper onto a mold or shape to make it hard and stiff. After the glue dries, you can decorate your tiara with paint, stickers, glitter or anything shiny to make it look pretty. It's a fun activity because you can make a tiara that's unique and customized just for you!
