Your Host: Kathryn Costa

Hi I'm Kathryn Costa, your host of the 100 Mandalas Sharing Circle. In 2015, I opened the doors to the first Sharing Circle, a place for mandala enthusiasts to share the mandalas they were creating for the 100 Mandalas Challenge. Since then we've collaborated on group mandala projects and gathered for online mandala parties and events. You don't have to take the 100 Mandalas Challenge to join. The Sharing Circle is for you if you love to color mandalas, create your own designs, or curious about your mandala stories.

There's a place for everyone in the circle at 100 Mandalas.
