Five-Oh is a really fun way to create borders for your Zentangle tile, and it’s quite flexible in its use. You can also create “waves” around the edges. There really is much to be explored here.
My advice is to simply pick a starting point and go for it. Make some big waves, make some smaller ones.
Use these tiles to create some Five-Oh inspired borders. What other tangles can you use to create a visually interesting piece?
