A couple of months ago I was able to download, for free, many stock images from GraphicStock. I will admit that it sucked up many hours of my time looking through thousands of their images for designs I liked that would lend themselves to adding tangles. I think it was worth it. Here's one of them, as it was downloaded.
And here's what I chose to do with it. I was unsure if I should add more tangling on the right side of the circle, but when I took a vote of family members the clear answer was to leave it as is. I do love the way it looks, but sometimes I'm just not sure when to stop.
Here's another one of the images, with lots more color. The before...
And the after...
The wavy design reminded me of the line drawings I've been working on recently, so I started by mimicking the feel of those lines. Then I added Rixty, put auras around some of it, and continued the line work around to enclose the Rixty. Interesting, but not sure if I love it. I could try printing this design again and do something completely different with it. Not a bad idea... we'll see.
It's really fun to take an image and add your own Zentangle touches to it. You should give it a try if you haven't already.
