Maybe not enough people showed up to your barbecue. But at least you can use the leftover plates to make these adorable heart crowns (swipe out the heart for any shape to match the holiday! Shamrock for St. Patrick's Day. Tree for Christmas. The possibilities are endless!)
We all know the Thanksgiving Turkey hand, but it's about time that other holidays got in on the finger painting fun. If you don't want to get your hands messy, you could also trace your hands onto construction paper, like this.
You can find a heart-shaped hole puncher in any craft aisle, and free paint samples in any home improvement store. But if you're going to make a bunch, it's probably a good idea to hit multiple home improvement stores. Free doesn't mean getting greedy.
