The Diva's Weekly Challenge #277: Running 'round in Circles
The featured tangle this week on our Facebook group 'Square One: Purely Zentangle' is echoism which is really hard to see on this tile but it's hidden in there. If you are not sure what it looks like click on Tanglepatterns.
I decided to draw echoism around a circle so it worked really well for The Diva's challenge as well. It was funny how echoism disappeared by filling in the spaces and had to have another go with colour on a Zendala.
