Trevor and I collected these:
And painted them red. (For the record, it takes about 7 coats of paint to get a nice even topcoat.) Here are Trevor's.
My idea was that these four rocks could hold down the corners of the tablecloth on the main table so that it doesn't lift up or blow away.
Trevor and I drew noses and mouths on our red rocks with a Sharpie, then I sprayed them with a clear sealant. We found googly eyes, and cut green felt to make the leaves and stems. I attached the eyes and felt with a hot glue gun.
Trevor's two are on the left; mine are on the right.
Aren't they cute?! I'm strongly considering making some for myself. I could use something adorable to hold down our tablecloth or picnic blanket when we eat outdoors. They would also make a cute gift.
