With some imagination you can use modeling clay to create garden scenes and representations of things you would find in a garden. Cut a block of clay into small clay bricks, and create your own garden wall. You can use bricks to make other garden pieces, such as a wishing well, a park bench and a small garden shed. Use different-colored clay to make a brick path in your garden scene, and you can also create trees and other foliage. Once you get started creating your own clay garden, it can be fun to see where your imagination will take you. Also clay pots, large & small ones. There's more online, good luck.
