We had so much fun making these! They are just melted plastic beads. We’ve done them in cake pans and also using metal cookie cutters on a cookie sheet. You can make a hanging hole in them using a marble. Arrange the beads – or just dump them in – then bake for 20 minutes at 425. Do NOT use beads with any sort of coating or paint – the fumes are horrible! There will be slight fumes regardless, so open the house up. Super easy and both kids and adults have fun making them.
