Zentangle Challenge #74 - Eccentric Circles

The Zentangle Challenge (www.iamthedivaczt.blogspot.ca) for this week is to draw "eccentric" circles for our string. I decided that instead of drawing irregular circles, I would draw circles (ovals) in one direction, then draw some others in another direction. This led me to wanting to "weave' the lines. I've used two new to me tangles, Purk and Wartz. I'm not entirely happy with this, especially Bilt which didn't turn out or float the way I wanted it to; and it's rather hard to see how the circles interweave. Oh well - at least I learned two new tangles. Thanks in advance to anyone who takes the time to post comments - they are much appreciated. Have a good rest of the week.
