I made quick and easy washi tape crowns for my girls a few days back. I let the girls choose the tapes they wanted on their crowns so that they felt they could be part of the fun process as well. At least I remember that choosing something wonderful was always fun when I was little.
All you need is a toilet paper roll, washi tapes, scissors and elastic cord. Tape the toilet paper roll with the washi tapes. Cut the roll into crown shape and poke small holes at the bottom.
