Here's a simple craft the girls and I did over the weekend with polystyrene balls, paper cups, acrylic paint and glitter. We did this especially for Jenna, who adores cupcakes.
First we cut the polystyrene balls in half. Then we cut the papercups down to size - so the polystyrene hemispheres could sit on the cups and not fall in.
Then we painted the hemispheres with acrylic paint.
We also painted the cups. Some of us used markers.
