Maria Thomas recently shared a new tangle she's called Aquafleur. It's quite lovely, both organic and bold. This new tangle is the Diva's challenge this week, which is wonderful as I had tried it once (in the lower right, here) and have been wanting to give it another whirl. You can find the how-to in the Zentangle newsletter here.
Here's my first tile, in black and white.
It's so lovely I thought it deserved to be tried in aqua, or water-y, colors so I did an acrylic wash and tangled on it.
For a really beautiful example of this tangle, see Carole Ohl's Christmas tree here.
