Zentangle is celebrating its 20th anniversary during 2025. As more tangles (patterns) have been added over the years so have the sizes, shapes and colors of the (paper) tiles. In addition to the variety of tiles, I like to tangle on gourds. scratchboards, clayboards, notebook covers, and cards. However, the sky is the limit as to what you can tangle on- quilts, stones, seashells, sneakers,  doors, furniture, bikes, cars, china, glass, jewelry ... whatever sparks the artist's imagination.
