I played with Zentangles (or Zentangle-Inspired-Art (ZIA), since they are not on 3 1/2" square tiles) again this week. I started with creating a string of a several circles of various sizes - a couple concentric circles and many overlapping circles. Then I tangled around the circumference of the strings or in the overlapping areas, rather than filling every open spot. It was challenging to find tangles that can be used for a border, rather than a fill. I had fun creating Wheels within Wheels.
After creating Wheels within Wheels, I wondered what other geometric shapes- squares, triangles, hearts - might turn out well for a similar ZIA. I chose squares and overlapped squares of various sizes. I created angles in the corners to fill, rather than following the contour of the perimeter, like I did with the circles. This is the result.
That is all I had time to complete for this week's challenge. I think heart shapes would be fun to do in this style, but not sure if I'll try the triangles. Hexagons are very popular in quilting right now, so maybe they would create an interesting ZIA in a similar design, too. I'll see what I'm inspired to sketch for Week 13!
