Thanks for this class, everything was so well explained. I enjoyed the new Tangle Voadora, while not a fan of straight line tangles like Paradox this one was easier to accompany understand. Thanks for exposing me to all straight lines, but It does come naturally to me.

As this was my first Eni Oken lesson, I was a bit overwhelmed - but in a good way1 I have watched sections many times and get something new out of it each time. Eni, you are so aware of making the lesson as accessible as possible. I love the constant opportunity for new learning! New tangles, A Frame, Anthem, Voadora, and new terms fore shortening and ICSO. All new faves ! Thank You ! Thank You ! Looking forward.......
