During the week of November 17 – 24, 2017, the challenge tangle for the Square One Zentangle group on Facebook was Dewd. As of this date, Dewd is the newest official Zentangle pattern. A step-out can be found here.
My Dewd tile appears below. The pattern is very close to aura’d Fescu (with a touch of sparkle) I think. The resulting look is simple and appealing, and I think that there is a botanical look to it. As is my tendency, I went for simplicity… in this case a monotangle. It almost looks like a bouquet!

Moving on, for the following week of November 24 – 30, 2017, the Square One challenge pattern was Zailz, by Loretta West CZT. A step-out can be found here.
When I looked at the Zailz step-out and other tiles, what I though of was an image of ocean waves cresting. Perhaps the Tipple (or Perfs) are bubbles? Anyhow, here is my Zailz tile:

Fins to the left, fins to the right? Or choppy seas? Fancy triangle shapes?
You decide. 🙂
