Z Challenge #113 Hip to be Square

I've been fascinated with the frames, or squares that have been popping up all over the Zentangle world lately. It got me looking at old frames even to the point as while on a 4th grade field trip to VT's State House, I was taking pictures of frames while everyone else was taking pictures of exhibits, people, etc. It's all about checking out the patterns!

This week's Diva Challenge is to create a square within a square within a square. Great. The outer square is inspired by one of the frames up in Montpelier at our State House.
Here's mine:
