Penny balls are quick and easy to make! They look beautiful in your garden, and they also repel slugs and will make hydrangea flowers blue.
I found many samples to inspire me on Pinterest, most made with bowling balls, but I thought Smoothfoam would be the perfect base for my penny garden ball. Weatherproofing the Smoothfoam with varnish will make it safe to use outdoors.
1. Spray the ball with brown spray paint and let dry.
2. Apply a coat of Marine Varnish over the entire surface of painted ball and let dry.
3. Glue the pennies to the ball and let dry.
