Build a Picnic Table
With Some HelpTalk to your parents before you start, and together check with the people responsible for the playground (usually town/city or school) to see if it’s okay to proceed.
Don’t have a picnic table to paint? Why don’t you build it yourself? You can either get a kit, or find some instructions online. A picnic table is a great way to help people to decide to spend more time at your playground!
