Challenge #122 Grid (un)-Locked

I am remembering back to Certification, close to the last day and a tangle was introduced based on a grid and I thought to my self "OMG, not another grid tangle"!

Well, I will tell you this exercise has totally changed my way of thinking.  As soon as it was mentioned on the Zentangle blog I started a grid on scratch paper and had a go.  The grid keeps getting larger as I think of things.  I wish I had started it in my journal.

When I finally sat down to do a tile I still had the grid on my mind.  An uninteresting string, but I do like the way it came out.

And another one.  So much fun!
