These are patterns I've come up with. As I don't own every Zentangle book yet, I'm crossing my fingers that what I post here is different enough to be a new pattern (I've researched at TanglePatterns.com pretty heavily).
Disclaimer: if any of these patterns already exist somewhere, please let me know so I can revise and give proper credit. I've noticed that patterns can have similarities without being tangleations and/or can be considered new if they are different enough.
That said, here they be. They're permalinks to the page where the pattern debuted.
