Large sphere molds can be very difficult to find. At History Stones we sell 10", 12" and 15" diameter molds. We often receive requests for larger spheres, so we decided to use a yoga ball as a mold and share this project!
Check out this video above to learn how to make your own! I have also included step by step instructions below.

Place the yoga ball on a bucket, with a wire ring around the edge.

Connect an air hose to the yoga ball. When your project is finished and dried you will use this air hose to deflate the yoga ball and remove it!

Cut the adhesive mesh into strips half way down the ball. Then wrap the pieces around the wire ring.

Then use some of the small adhesive mesh to tighten up and secure the larger pieces.

Spread thin set over the mesh by hand. You will have to wait at least 6 hours and repeat this process three times so that you have at least three layers of thin set. The more layers the stronger and better!

Wait at least 24 hours after your last layer and deflate the yoga ball. Remove the yoga ball from the sphere, and you are almost done!

Now for the fun part! You can paint your sphere, keep it white and use a sealer, or use acid stain... Whatever your heart desires. We decided to use Brickform acid stains in coffee and olive. To achieve the drippy look pour some of the acid stain in spray bottles.

Let your masterpiece dry and you are done!! You can fill the ball with soil and plant something beautiful inside, or leave it as a sphere.

    Would love to see it in service with plants. How does It not it's roll away, do you sink it in the ground?

    what is the wire ring for? After you remove the yoga ball, is the sphere heavy, will it break easily like an egg shell?
